rear suspension lower control arms inner bushes, the factory ones are pressed out and the new offset bushes ( Poly) are pressed in, the instructions say you can do it on the car.

but thats not the case you need to remove them

the the factory bushes have an eccentric/offset bolt whereas the KMAC kit has an offset hole and the whole bush is able to rotate in the shell to allow for camber adjustment. allowing for vastly more range of adjustment. in my case the wear on the rear tyres was acceptable and the stock height, however once lowered there was insufficient scope for adjustment to correct the now excessive rear camber, hence the reason i went with the kit.

in my case i now have 0 camber so perfect wear across the tyres ( 315,s) however as i said earlier if i find the front wearing faster than the rear i will get some negative camber dialled in to the back. to even the wear and to improve handling.

the negative camber in BMW,s is there for a reason , and in my case now i feel the car has lost a marginal amount of cornering ability with the 0 camber.

its a balancing act for a road car between camber and tyre wear,
