The E82 and E90/E92 subframes have an inherent weakness in the rear subframe - the mounts are too soft for the power and torque these cars are capable of. The subframe is the heart of a BMW's rear suspension. As torque is transmitted through the differential and axles and as the tires grip the road, the subframe mounts are working to keeping everything in line. That's a tough task to hold when torque is increased with bigger boost (335i) or even mild tweaks (M3). While the M3 subframe mounts are a great upgrade for the non-M chassis these factory BMW Motorsport subframe mounts go one step further.
These Motorsport/Group N rear subframe bushings are a direct replacement upgrade over the stock mounts. They are rubber to conform to the rules of the Group N racing class - so they are still acceptable for street use as long as extra ride harshness can be tolerated. The rear subframe has to come down from the car for these mounts to be pressed in. So now is the perfect time to do other work as well - check out our other Motorsport Race bushings or M3 upgrades.
Price is for the set of 4 mounts.

Verkline's journey to develop an exceptional suspension set for the Supra A9X and BMW Z4 G29 began from day one, and it was significantly influenced by Robert from Apex Nürburgring YouTube video. With a profound understanding of high-speed driving dynamics, Verkline collaborated with Apex to craft a suspension set that pushes the boundaries of performance. Key Components in the Full Set: Rear Lightweight Tubular Subframe (WAS-401) Front Caster Adjustable Control Arms (WAS-410) Front Lower Adjustable Control Arms (WAS-411) Front Bump Steer Adjustable Tie Rod Ends (WAS-412) Front Sway Bar End Links (WAS-413) Rear Adjustable Traction Links (WAS-421) Rear Upper Adjustable Lateral Straight Links (WAS-422) Rear Upper Adjustable Lateral Bent Links (WAS-423) Rear Adjustable Toe Links with a lockout kit (WAS-424) Rear Spring Wishbone Bushings with lockout kit (WAS-425) Rear Knuckle Bushings (WAS-426) Rear Sway Bar End Links (WAS-427) Comprehensive installation and suspension setup instructions (66 printed pages) Toyota Supra A9X and BMW Z4 G29 were designed for an exhilarating driving experience on the streets, but their factory settings may not suffice for those seeking high-performance capabilities. The issue lies in rear-end bump steer, which affects the toe angle during suspension travel. The Consequences of Bump Steer: Rear toe changes unpredictably, impacting stability and handling. During hard acceleration, the rear end tilts, resulting in toe-in. Under hard braking, the rear suspension rises, leading to toe-out. Verkline's Solution: To address these issues and enhance performance, Verkline offers three suspension setup presets (Track, Street, Drag) tailored to various driving styles. These presets provide precise alignment, ride height suggestions, and arm lengths, ensuring optimal kinematics for every designated use of the car. Say goodbye to unpredictable handling issues and experience stable and controlled driving with Verkline's Suspension Set for Toyota Supra A9X and BMW Z4 G29. Transform your car's performance with the expertise of Verkline and Apex Nürburgring. Fits these models: Toyota Supra A90 Toyota Supra A91 BMW Z4 G29

Following extensive development and testing, Verkline is thrilled to introduce this cutting-edge rear subframe to the global automotive community. Crafted with precision and performance in mind, this subframe is the result of a comprehensive process that includes 3D laser scanning, CAD development, Finite Element Analysis (FEA) testing, and rigorous road trials. Key Benefits: Significant Weight Reduction: This lightweight subframe is 6.5 kg lighter than the OEM rear subframe, resulting in a remarkable 33% reduction in weight on the rear axle, delivering enhanced vehicle performance. Optimized Rear Final Drive Position: The rear final drive has been strategically repositioned 10 mm upward to alleviate stress on the C.V. joints. This adjustment safeguards against premature joint wear, especially when lowering the vehicle. Robust Mounting: The subframe has eliminated rubber mounts in favor of a single, bolted mounting position. This design choice prevents rear subframe shifts during high-load situations. Bump Steer Adjustment: The subframe is equipped with additional bump steer adjustment capabilities, enabling users to fine-tune the bump steer by adjusting the rear toe link pickup point up and down. Polyurethane Mounts: Factory rubber mounts have been replaced with race car-grade black polyurethane mounts, substantially reducing movement during torque transfer and improving drivetrain performance. Key Features: Ample Underbody Access: The subframe provides more space for underbody access, facilitating easier maintenance and upgrades. Enhanced Chassis Rigidity: Constructed with a tubular frame design using T45 tubing and S355 metal sheets, this subframe bolsters chassis rigidity for superior handling.
