I'm looking to convert my e36 328is front brakes to e46 330i fronts. Do I just need the rotors calipers and pads? Also is there any way to upgrade the rears and still retain the parking brake? I've searched and couldn't seem to find that it had been done successfully.
I don't have any specific I don't have any specific experience with that to be able to help you out - if you can find out if the calipers and rotors will bolt up, then obviously that could work. Things I can think of that could be a problem - different rotor thickness; if the e46 rotor is thicker, you might be slightly affecting wheel offset, and you might need longer lug bolts, and possibly a longer rotor set-screw. Possible brake-bias issue as well? I'd suggest asking some real brake experts if going this route may accomplish what you want (Bimmerworld, or Turner, for instance). It may be that the difference is nominal enough that it's not worth the conversion, and if you really need a significant boost in braking performance, it would be better to go with a dedicated big-brakes kit. Depends on what you're hoping to get here, and why. Hitting the track is one thing, vs. only street-driving.
Hi there! The best advice I can give you is to check out Turner Motorsports' "brake upgrade kits". They start at about $380 and will include new rotors (cross drilled or gas slotted), ss braided lines, your chice of pads and a can of hi perf/hi temp brake fluid. For a couple bucks more, you can order the caliper rebuild kit. I got it for my E30 and is already on the "wishlist" for my "new" E36 M3. Hope this helps!
