The 330ci gets new rear control and trailing arm bushings, as well as some trailing arm reconditioning to make things look nice.
The trailing arm bushings are from Condor Speed Shop and are offset to account for the extra toe in from lowering the car. Originally, only the upper outer control arm bushing is spherical, but the same exact bushing will fit the lower as well as an upgrade, and is how the M3 is setup. The upper inner is from Powerflex, and is a mild upgrade, mostly to replace the worn stock ones.
I removed the brake rotor shields and parking brake components since they aren't necessary. With a race car, it's unlikely it'll be left running on an incline without anyone in it.
