VEEDUBBED 0 Posted July 14, 2014 Guys, What master cylinder is needed for the Audi G60 front caliper upgrade? It's probably been asked loads but i can't find a definitive answer regarding the master cylinder bore size. I've got an ABS equipped corrado, is the MC's bore sufficent or do i have to buy a MC off an ancient Audi quattro or 100 that's got a 24mm bore MC. Anyone actually done it?
