Drastically improve the acceleration of your BMW F20 M135i/M140i with our Suspension Secrets BMW F20 M135i/M140i Adjustable Rear Traction Arms / Links.

Our solidly mounted arms are designed to extract the most amount of traction from your BMW's rear axle. They offer the following benefits:

• Greatly improved acceleration
• Increased straight line stability
• More responsive rear axle to throttle inputs
• Reduced unwanted toe flex during throttle applications
• Higher corner exit speeds

We designed our adjustable rear traction arms with strength and ease of adjustment in mind. Our solidly mounted arms replace rubber bushed OEM BMW arms, and as a result our arms do not flex during throttle applications, which makes the rear axle far more responsive to throttle usage, whilst removing unwanted toe angle change.

The Suspension Secrets BMW F20 M135i/M140i Adjustable Rear Traction Arms can be adjusted with a 17mm spanner, allowing you to finely tune them in order to control the rotation of the wheel hub as the car accelerates.
