Suspension Secrets Front Offset Caster Bushes – BMW M3 (F80)/M4 (F82)

Sharpen the steering and improve stability with Suspension Secrets Front Offset Caster Bushes for the BMW F80 M3 and F82 M4.

The OEM front control arm bushes are made from soft rubber that flexes during cornering and hard braking. This leads to vague steering feel, understeer, and instability.

Our solid caster bushes solve these issues by eliminating bush flex, giving you a more direct connection to the road. The offset rose joint design increases positive caster, improving steering feel, dynamic camber gain, and overall front-end grip.

These bushes are also ideal for cars running camber/caster adjustable top mounts. They help realign the front wheels in the arch, preventing rubbing on the inner arch liners—especially when dialling in maximum caster.

Benefits:

• Increased cornering grip through added positive caster

• Sharper, more responsive steering

• Improved braking stability

• Allows max caster setup without wheel arch rubbing

• Full control over front suspension geometry
