Hey guys,

I just installed a set of factory MZ4 offset bushings on my newly acquired ZHP. I have a couple MZ4 racecars at the shop and I noted the bushings on those cars looked like they would fit. So I special ordered a set from my BMW dealership. I Pressed out the old bushing from the bushing bracket, and installed the new bushings.

First impressions, the car tracks and feels way more confident and positive though the steering wheel. The extra caster the bushings provide gives more positive feel. Under braking the "numb" feel is gone, they make threshold breaking easier to achieve.

Anyway, here is the Real OEM diagram I found the part number on.



Number 9
09 SET RUBBER MOUNTING D=66MM 1 31107838575 $75.19

Party on fellow motorists. Hope you guys find this helpful!
