A modification package designed to transform a Subaru vehicle from its factory-standard all-wheel drive (AWD) configuration to a rear-wheel drive (RWD) system. Such a package typically includes components necessary to disable the front drivetrain, reroute power solely to the rear wheels, and potentially address any resulting mechanical or electronic imbalances. As an example, a kit might consist of a modified or replaced transmission tailshaft, front axle removal components, and electronic control unit (ECU) recalibration to prevent error codes.
The motivation behind altering the drivetrain stems from several factors. Some enthusiasts seek improved handling characteristics more akin to traditional sports cars, finding RWD provides a more engaging and potentially predictable driving experience, especially in performance driving scenarios like drifting. Furthermore, a reduction in drivetrain components can lead to a slight decrease in vehicle weight and potentially improved fuel economy, although these benefits may be marginal. Historically, the conversion has been a niche modification, primarily pursued by individuals interested in motorsport or those seeking a unique driving dynamic.
Understanding the implications of this modification requires exploring the mechanical changes involved, the potential effects on vehicle warranty and reliability, and the various applications for which such a conversion is deemed suitable. The subsequent discussion will delve into these aspects, providing a more thorough assessment of the advantages and disadvantages of altering a Subaru’s drivetrain in this manner.
1. Drivetrain modification
The heart of any vehicular transformation lies within its drivetrain, and when considering the shift from Subaru’s signature all-wheel-drive to a rear-wheel-drive setup, the drivetrain modification becomes not merely a component swap, but a philosophical shift in how the vehicle interacts with the road. This core alteration touches every aspect of the car’s behavior, demanding a thorough understanding of its implications.
-
Front Axle Disconnection
The initial step involves physically disconnecting the front axles from the drivetrain. This might seem straightforward, but it carries significant weight. Simply removing the axles without addressing the open front differential creates a situation ripe for mechanical failure. The differential, designed to distribute power between wheels with varying traction, will now spin freely, generating heat and potentially catastrophic wear. The solution often involves either welding the differential to lock it, preventing rotation, or replacing it with a solid stub axle. The choice depends on the intended use, with a locked differential being a less refined but more robust solution for purely performance-oriented vehicles.
-
Transmission Tailshaft Adaptation
Subaru transmissions are inherently designed to route power to both front and rear axles. To convert to rear-wheel drive, the tailshaftthe output shaft that normally connects to the front differentialrequires modification. Some kits may involve replacing the entire tailshaft with a unit designed solely for rear-wheel drive output, eliminating the front drive gears entirely. Others might employ a blanking plate to seal off the front output and prevent fluid leakage. The integrity of this modification is critical; a failure here could result in complete drivetrain loss, leaving the vehicle stranded.
-
Center Differential Management
The center differential, or transfer case, plays a crucial role in splitting torque between the front and rear axles in the original AWD configuration. When converting to RWD, this component must be effectively managed. In some cases, it’s mechanically locked, forcing 100% of the torque to the rear. However, this approach can place undue stress on the rear differential and axles. A more sophisticated approach involves replacing the center differential with a custom unit designed to function solely as a rear-wheel drive output, maintaining proper lubrication and preventing internal damage. The selected method directly impacts the long-term reliability and performance of the converted drivetrain.
-
ECU Recalibration
Modern vehicles rely heavily on electronic control units to manage various functions, including the drivetrain. Converting to RWD often triggers error codes due to the absence of front axle rotation sensors or other AWD-related inputs. ECU recalibration is essential to prevent these errors and, more importantly, to optimize the engine and transmission performance for the new drivetrain configuration. This may involve disabling certain AWD-related parameters, adjusting fuel maps, and fine-tuning shift points to suit the RWD setup. Neglecting ECU recalibration can result in reduced performance, poor fuel economy, and even damage to the engine or transmission.
These modifications, each a critical step in the process, collectively redefine the vehicle’s dynamics. The decision to undertake such a conversion is not merely a matter of swapping parts; it’s a commitment to fundamentally altering the car’s character. The success of the transformation hinges on meticulous planning, precise execution, and a thorough understanding of the interconnected nature of the drivetrain components.
2. Handling dynamics
The essence of driving often distills to the interaction between vehicle and road, a dance governed by handling dynamics. With a Subaru, inherently all-wheel drive, that dance is predictable, surefooted, almost democratic in its distribution of power. A conversion to rear-wheel drive throws a wrench into this equilibrium, creating a new, more demanding choreography. It’s a shift from stability to potential instability, from reassurance to a constant negotiation with physics.
-
The Pendulum Effect
AWD Subarus, when pushed, tend to understeerthe front wheels lose grip before the rear, causing the car to resist turning. It’s a safe, if uninspiring, characteristic. RWD flips this script. Now, the rear wheels are the primary drivers, and when they lose grip, the car oversteers. The tail swings out, like a pendulum released, requiring skilled counter-steering and throttle control to manage. This newfound propensity for oversteer demands a recalibration of driving reflexes, turning what was once a point-and-shoot experience into a constant exercise in car control. Imagine navigating a tight corner in the rain: the AWD Subaru would grip and pull through; the RWD conversion could easily break traction, requiring a delicate dance to avoid spinning out.
-
Weight Transfer Amplified
Weight transfer is ever-present in driving acceleration shifts weight to the rear, braking shifts it forward, and cornering transfers weight to the outside wheels. In an AWD car, the distribution of power helps mitigate the effects of these shifts. With RWD, weight transfer becomes more pronounced and impactful. Under acceleration, the rear wheels are now solely responsible for putting power down, and any sudden weight shift can easily overwhelm them, leading to wheelspin and loss of control. The driver must learn to anticipate and manage these shifts with precision, using throttle modulation and steering input to maintain balance. Picture a drag race: the AWD Subaru launches with minimal wheelspin; the RWD conversion requires careful throttle control to prevent smoking the tires and losing valuable time.
-
Steering Feel and Feedback
One often-touted benefit of RWD is improved steering feel. With the front wheels no longer burdened by driving duties, they are freed to focus solely on steering. This can result in a more direct and communicative connection between the driver and the road. The steering wheel transmits more nuanced information about the tires’ grip levels, allowing for more precise corrections and adjustments. However, this increased sensitivity also demands greater concentration. The driver must be attuned to the subtle cues from the steering wheel, constantly interpreting the road’s surface and the car’s behavior. Think of navigating a winding mountain road: the AWD Subaru offers consistent, if somewhat muted, steering; the RWD conversion provides a richer stream of feedback, allowing for more precise placement and control.
-
Suspension Tuning Becomes Critical
The factory suspension settings on an AWD Subaru are designed to complement the car’s inherent stability. Converting to RWD necessitates a reevaluation of these settings. Spring rates, damper settings, and sway bar stiffness all play a crucial role in managing the car’s newfound oversteer tendencies. Stiffer rear springs and dampers can help control body roll and prevent excessive rear-end squat under acceleration, while adjusting sway bar stiffness can fine-tune the car’s balance. Without proper suspension tuning, the RWD conversion can feel twitchy and unpredictable, making it difficult to extract the full potential of the new drivetrain layout. Envision a track day: the AWD Subaru handles predictably, but the RWD conversion, if not properly tuned, could exhibit snap oversteer, making it challenging to maintain a consistent line.
These interwoven aspects of handling dynamics are intrinsically tied to the alteration introduced by the “subaru rwd conversion kit.” The kit is not merely a collection of parts; its the key to unlocking a different dimension of driving, one that demands respect, skill, and a deep understanding of the forces at play. The conversion transforms the Subaru from a vehicle of inherent stability into a tool for precision and expression, a canvas upon which the driver paints their driving style.
3. Performance enhancement
The allure of increased performance often whispers to automotive enthusiasts, a siren song promising greater speed, sharper handling, and an overall enhanced driving experience. For Subaru owners, the path to this heightened performance sometimes leads to a fundamental alteration: a rear-wheel-drive conversion. While the manufacturer designed these vehicles with all-wheel drive as a core attribute, the notion of unlocking latent potential through a drivetrain transformation has gained traction within certain segments of the Subaru community. The following points illuminate how such a conversion is pursued under the banner of performance enhancement.
-
Weight Reduction and Drivetrain Loss
One enduring argument centers on weight. All-wheel-drive systems, by their nature, incorporate additional components: front differentials, axles, transfer cases, and associated hardware. Removing these elements sheds weight, however marginally. This lighter curb weight theoretically translates to improved acceleration and braking. Furthermore, the complex power distribution inherent in AWD introduces drivetrain loss, consuming some of the engine’s output before it reaches the wheels. By simplifying the drivetrain to RWD, proponents suggest a reduction in this parasitic loss, allowing more power to be directly applied to propulsion. Consider a scenario: a modified WRX, traditionally known for its AWD grip, undergoes the conversion. The owner reports a slight uptick in responsiveness and a sensation of increased power delivery, albeit often subjective and difficult to quantify on a dyno.
-
Enhanced Drifting Capability
For those drawn to the art of controlled slides, the conversion unlocks a completely different dimension of performance. All-wheel-drive, while excellent for traction, inherently resists drifting. The front wheels constantly attempt to pull the car straight, counteracting the desired yaw angle. Converting to RWD allows for the effortless initiation and maintenance of drifts. The rear wheels, now solely responsible for propulsion, can be easily overwhelmed, breaking traction and sending the car into a slide. The skill then lies in modulating the throttle and steering to control the angle and trajectory. Imagine a Subaru BRZ, a purpose-built RWD sports car, demonstrating its drifting prowess. The converted Subaru seeks to emulate that agility, becoming a tool for stylistic expression on the track or in controlled environments.
-
Simplified Forced Induction Integration
High-horsepower builds often involve forced induction: turbochargers or superchargers. In some cases, the integration of these systems is simplified with a rear-wheel-drive configuration. The reduced complexity of the drivetrain allows for easier routing of exhaust components and intercooler piping. Furthermore, the absence of a front differential can free up valuable space in the engine bay, providing more room for larger turbochargers or custom manifolds. Envision a highly modified STI aiming for extreme horsepower numbers. The conversion streamlines the engine bay, making space for a larger turbo and allowing the builder to optimize the exhaust flow for maximum power output.
-
Track Day Optimization
On a closed circuit, the dynamics shift. While AWD provides an advantage in slippery conditions or during initial acceleration, RWD can offer superior balance and predictability in cornering, especially on dry pavement. The removal of the front drivetrain reduces understeer, allowing the car to rotate more freely into corners. This, in turn, can translate to faster lap times for experienced drivers who can exploit the RWD layout’s inherent agility. Picture a converted Subaru competing on a track day. The driver, accustomed to the AWD’s surefootedness, initially struggles with the RWD’s oversteer tendencies. However, with careful adjustments to suspension and driving style, they begin to unlock the car’s potential, achieving faster cornering speeds and improved overall lap times.
It is crucial to acknowledge that these perceived enhancements are not universally applicable. A rear-wheel-drive conversion is not a guaranteed path to superior performance for all drivers or in all situations. The benefits are often contingent on the driver’s skill level, the specific application, and the quality of the conversion components. Ultimately, the decision hinges on a clear understanding of the trade-offs and a realistic assessment of the desired outcome. The siren song of performance enhancement can lead to a satisfying journey, but only if the destination is clearly defined and the path is carefully navigated.
4. Component compatibility
Within the realm of Subaru rear-wheel-drive conversions, component compatibility stands as the silent guardian of success or failure. It is not merely a matter of bolting parts together; it’s an intricate dance between existing infrastructure and aftermarket aspirations. A misstep in this compatibility ballet can lead to mechanical discord, financial setbacks, and a compromised driving experience.
-
Transmission Harmony
The Subaru transmission, originally designed to apportion torque between front and rear axles, becomes the focal point of transformation. Kits often necessitate modifications to the tail shaft, or even complete transmission swaps. The challenge lies in ensuring the replacement components seamlessly integrate with the existing gear ratios and electronic control systems. For instance, attempting to mate a high-performance kit designed for a five-speed transmission to a six-speed variant could result in catastrophic failure, leaving the conversion incomplete and the vehicle immobile. The transmission, in this context, is the heart of the conversion, and its compatibility dictates the rhythm of the entire powertrain.
-
Differential Dynamics
The rear differential, now the sole recipient of engine power, must be capable of handling the increased load. Stock differentials, particularly those from lower-trim models, may not withstand the strain of spirited driving or forced induction. Upgrading to a limited-slip differential (LSD) is a common practice, but the choice of LSD must align with the intended use. A clutch-type LSD, aggressive and responsive, may be suitable for track use but harsh for daily driving. Conversely, a Torsen-type LSD, smoother and more predictable, might be preferred for street applications. The differential, in this narrative, is the anchor point, ensuring the power is delivered effectively without succumbing to undue stress.
-
Axle Integrity
The axles, responsible for transmitting torque from the differential to the wheels, are often overlooked until they become the weak link in the chain. The increased stress of RWD, particularly under hard acceleration or drifting, can quickly expose any deficiencies in axle strength. Upgrading to heavy-duty axles, designed to withstand higher torque loads and increased angular deflection, becomes a crucial consideration. A snapped axle on the track is not merely an inconvenience; it’s a safety hazard, a stark reminder of the importance of component compatibility. The axles, in this narrative, are the messengers, ensuring the power reaches its destination without faltering.
-
Electronic Synchronization
Modern vehicles are governed by intricate electronic systems, and a rear-wheel-drive conversion can disrupt this delicate balance. The absence of front-wheel speed sensors, for example, can trigger error codes and disable traction control systems. Electronic control unit (ECU) recalibration is often necessary to compensate for these changes and ensure proper vehicle functionality. Failure to address these electronic nuances can result in diminished performance, reduced fuel economy, and even potential damage to the engine or transmission. The ECU, in this context, is the conductor, orchestrating the various systems to work in harmony. A discordant ECU can undermine the entire conversion, leaving the vehicle out of tune.
These considerations underscore the importance of meticulous planning and careful component selection when embarking on a Subaru rear-wheel-drive conversion. The phrase serves not just as a label for a kit, but as a reminder that the journey is as much about integration as it is about modification. A harmonious blend of existing systems and aftermarket components ensures not only optimal performance but also the long-term reliability and enjoyment of the transformed vehicle. The narrative of component compatibility is one of prudence, diligence, and a deep respect for the interconnectedness of mechanical and electronic systems.
5. Installation complexity
The allure of transforming a Subaru from its all-wheel-drive origins to a rear-wheel-drive machine often overshadows a critical aspect: installation complexity. The degree of difficulty involved is not merely a procedural hurdle; it represents a significant gatekeeper dictating who can successfully navigate this mechanical metamorphosis. The conversion kit, in essence, is a roadmap, but the terrain it traverses is fraught with potential pitfalls for the uninitiated. Incorrectly installed components can lead to catastrophic mechanical failures, rendering the vehicle inoperable or, worse, creating a dangerous driving situation. Consider the narrative of a weekend mechanic, emboldened by online forums and a desire to unleash the rear-wheel-drive potential of their WRX. Armed with a kit and a set of tools, they begin the disassembly process. However, the nuances of differential removal, transmission modification, and ECU recalibration quickly become apparent. Without proper knowledge and experience, critical steps are missed, torque specifications are ignored, and the project stalls, leaving the vehicle stranded on jack stands and the owner facing a daunting repair bill.
The complexity extends beyond mere mechanical aptitude. It necessitates a deep understanding of vehicle dynamics, drivetrain architecture, and electronic control systems. For example, a seemingly straightforward step like disabling the front axles can have unforeseen consequences if the center differential is not properly addressed. A mismatched transfer case or improperly calibrated ECU can lead to erratic shifting, reduced power output, and even damage to the transmission. The practical significance of understanding this complexity lies in the ability to assess one’s own skill level and determine whether professional assistance is required. A candid self-assessment can prevent costly mistakes and ensure the conversion is executed safely and effectively. Furthermore, it highlights the importance of selecting a reputable conversion kit with comprehensive instructions and readily available technical support. The clarity of the documentation and the responsiveness of the manufacturer can be invaluable resources when navigating the intricacies of the installation process.
In conclusion, the installation complexity inherent in a Subaru rear-wheel-drive conversion serves as a vital filter, separating those who are adequately prepared from those who are not. It is a testament to the intricate interplay between mechanical systems and electronic controls, demanding a holistic understanding of the vehicle’s architecture.

6. Reliability implications
The transformation of a Subaru from its factory-standard all-wheel-drive configuration to a rear-wheel-drive system, while potentially enhancing performance characteristics, introduces a host of reliability implications that demand careful consideration. This conversion is not merely an alteration of drivetrain components; it’s a fundamental shift in the vehicle’s engineering, with potential long-term consequences for its mechanical integrity. Neglecting to address these implications can lead to premature wear, increased maintenance demands, and a shortened lifespan for critical components.
-
Increased Stress on Rear Drivetrain
The Subaru’s original AWD system distributes torque across both axles, mitigating stress on individual components. Converting to RWD concentrates the entire engine output onto the rear drivetrain. This places significantly higher loads on the rear differential, axles, and associated bearings. A differential designed to handle 50% of the engine’s torque is now tasked with managing 100%, potentially exceeding its design limits. Over time, this increased stress can lead to premature wear and eventual failure. The axles, too, become more vulnerable. Their twisting and bending forces increase proportionally, making them susceptible to snapping under hard acceleration or during aggressive maneuvers. Consider the case of a converted WRX subjected to frequent track days: the rear differential, originally intended for moderate street use, succumbs to the relentless strain, necessitating a costly rebuild after only a few months of operation.
-
Compromised Factory Safety Systems
Subaru vehicles are equipped with a suite of electronic safety systems, including traction control, stability control, and anti-lock brakes, all calibrated to function in conjunction with the AWD system. A rear-wheel-drive conversion can disrupt the effectiveness of these systems, potentially compromising vehicle safety. For example, the stability control system relies on wheel speed sensors to detect and correct for skidding. When the front wheels are no longer driven, the system may misinterpret sensor readings, leading to inappropriate interventions or even complete system failure. In adverse weather conditions, this loss of stability control can significantly increase the risk of accidents. Imagine a converted STI encountering black ice: the stability control system, designed to react to subtle variations in wheel speed across all four wheels, struggles to interpret the lack of input from the front axle, resulting in a delayed or ineffective response, potentially leading to a loss of control.
-
Potential for Transmission Damage
The transmission, originally engineered to transfer power to both front and rear differentials, faces new challenges in a rear-wheel-drive configuration. Certain conversion methods involve locking the center differential, forcing all engine torque to the rear. While seemingly straightforward, this approach can place undue stress on the transmission’s internal components, especially under high-load conditions. The constant strain can lead to accelerated wear on gears, bearings, and synchros, ultimately resulting in transmission failure. Moreover, the absence of front-wheel drive can alter the transmission’s lubrication patterns, potentially starving certain components of vital oil. Picture a converted Forester embarking on a long road trip: the transmission, subjected to prolonged periods of high-speed cruising with a locked center differential, begins to exhibit signs of distress, with increasingly difficult shifting and a noticeable whine emanating from within, foreshadowing an impending breakdown.
-
Voided Warranty and Reduced Resale Value
Performing a rear-wheel-drive conversion typically voids the factory warranty, leaving the owner responsible for any subsequent repairs. Subaru, like most manufacturers, does not cover modifications that deviate significantly from the original design specifications. This means that any mechanical failures directly or indirectly related to the conversion will not be covered under warranty, potentially leading to substantial out-of-pocket expenses. Furthermore, a converted Subaru may experience a reduction in resale value. While some enthusiasts may appreciate the unique nature of the modification, the majority of potential buyers are likely to be wary of a vehicle that has undergone such a significant alteration, perceiving it as less reliable and more prone to problems. Consider a meticulously maintained WRX, a prized possession before the conversion. Upon attempting to sell the vehicle, the owner discovers that prospective buyers are hesitant, citing concerns about long-term reliability and the absence of a factory warranty, ultimately forcing a lower selling price.
These multifaceted reliability implications underscore the importance of approaching a Subaru rear-wheel-drive conversion with careful planning, informed decision-making, and a realistic assessment of the potential trade-offs. The conversion is not a guaranteed path to enhanced performance; it is a complex modification with inherent risks that must be thoroughly understood and addressed to ensure the long-term reliability and drivability of the vehicle. The siren song of rear-wheel-drive dynamism must be tempered with a pragmatic understanding of the potential consequences for the vehicle’s mechanical integrity.
