SPL Parts Adjustable Rear Traction Links / Control Arms - SPL RTR F8X

The SPL Parts Adjustable Rear Traction Links (Part #SPL RTR F8X) are engineered to improve rear-end stability, traction, and suspension response on BMW F8X and G8X M cars. By eliminating factory rubber bushing deflection, these traction links reduce wheel hop under hard launches and maintain consistent rear suspension geometry during aggressive acceleration and braking.

Length adjustability allows fine tuning of rear bumpsteer and anti-squat characteristics, making these arms ideal for high-performance street driving, track use, and competitive motorsports applications.
