Best Brake caliper for Volkswagen Golf

I'm not going to get in to what bolts on directly since I love the g60 set up on a mk2. But i will say that anytime you upgrade one part of your brake system some other part will suffer.

First of all, you can run the G60 (Girling 54) fronts with rear disk on a 20mm master cylinder with no problem. I am running that setup right now. That being said, yes, the pedal feel would be nicer with a 22mm master, but the 20mm will work also.

Braking is sure, thanks to large four-piston calipers all around, though the pedal effort is not as progressive as I'd like.
