I tried searching, but couldn't find a definitive answer on this.
I've been shopping around for options for upgrading the OEM brakes on 80 and while I've found upgrades, rotors, pads, and lines, I haven't been able to find anything about calipers. Parts are already hard to find for this car; performance parts and upgrades are damned near impossible, it seems.
I'd really like to upgrade the brake booster and calipers on the car, along with everything else, as the brakes currently are a little mushier than I like and I get some pretty serious brake fade at times. It currently has solid rears and vented fronts, with single piston calipers all around.
My three main questions are thus:
1) Is there somewhere that I can buy upgraded 2-piston calipers that will fit on my car? What about a stronger brake booster?
2) Is it possible to upgrade the solid rear rotors to vented rotors? I realize the OEM caliper is fitted for solids on the rear, but maybe aftermarket calipers could fit vented.
3) What about a full brake system swap? I've heard of people swapping A6 and S4 brakes onto their B4 90's and Coupes, but nothing about B3's, and especially nothing about 80's. What brake systems would be interchangeable or fit onto my B3 80? I'm doing the work myself and do not have access for fabricators or welding equipment, so anything suggested would need be essentially bolt-on.
