Suspension Secrets BMW G80/G81 M3 & G82/G83 M4 Front Offset Caster Bushes

Optimise your G8X M3 or M4’s steering feel and high-speed stability with the Suspension Secrets Front Offset Caster Bushes, designed specifically for the BMW G80/G81 M3 and G82/G83 M4. These precision-engineered bushes increase front caster by approximately 1 degree, enhancing steering response, mid-corner stability, and front-end grip without compromising ride comfort. By correcting the geometry of the front suspension, they allow for more consistent tyre contact and better feedback through the steering wheel—perfect for both spirited road driving and track use.
