With regards to 330 brake upgrade, is it worth doing the rears as well? I have read that there are 3 rear brake upgrades possible for it:
1. E36 'vert rear brakes 276x19 vented.
2. E46 325/328 'vert rear brakes 294x19 vented
3. E46 330i/ci rear brakes 320x20 vented
Will there be noticeable difference with any of the above fitted. When the braided brake lines were installed a brake bias valve was fitted so adjustments can be made to front or rear.
