Suspension Secrets Adjustable Rear Traction Arms - BMW F87 M2 / M2 Competition

The standard bushes in the lower control arms on the BMW F87 M2/M2 Competition are made from soft rubber. This soft rubber flexes during cornering and heavy braking, causing the front toe geometry to change dynamically as the rubber flexes. The constantly changing toe angles causes your BMW's steering to feel vague and inaccurate, and the changing toe also causes instability when braking hard.
