I know ;-) , the m3 control arm is angled differently as well, and changes the front camber as the front m3 spindles are different too.
I don't need these for my 318 which has new control arms.
I need these for a winter 325 which i didn't want to invest into, but after thinking about it, i think i am just going to buy a ebay kit with new control arms, lollypop bushings, stabilizer links, tierods and balljoints.
The front end is very loose in this car, and it bangs and vibrates at 100km/h, so its been staying to city driving only. Subframe bushings are fine on it etc, but if i have to remove the whole control arm i rather just replace the damn thing and the inner balljoints as well. I saved the spindles and hubs from my 318 when i did the m brake swap as they were new, so those went on the 325 already as the bearings and calipers were shot too. the shocks are new, spindles , hubs bearings, perfect calipers , but i was hoping the outball joints were not causing all the racket and that it was the bearings. well, it was both.
