Has anyone info, on converting the rear brakes on an 02 to disk? I have found only one person selling a Brembo conversion kit on Ebay, and nothing else. Is it possible and is it worth?
Ireland Engineering sells a kit using rotors and parking brake from a VW rabbit, check it out at bmw2002.com. I think it's worth it and I'm planning on doing it myself in the future. You may need a brake bias valve though and Ireland sells those as well.
Probably not worth the bother since rear brakes on the '02 don't have much to do. You can put E21 drums on (call them "Turbo brakes" since the 2002 turbo used the same ones ). They're a little bigger. You would do better to put together a set of '77 320i vented disks on tii struts in the front. That is an improvement.
I've got the E21 rear drums on mine already better than the original ones on the car but they still fade too quickly under repeated braking. I will look into the vented rotors though since I already have tii struts
One of our Gonzo-level drivers had a rear brake cylinder go bad last weekend on his 2002 track/autocross car. When he pulled off the wheel, I was surprised to see that he had drum brakes. Somehow you can make them work. http://www.flickr.com/photos/ovidiup/4099471543/sizes/l/in/set-72157622793347056/
