Project GTI 16V's 20mm master cylinder was pretty much dead. I replaced it with a 22mm unit from a later-model VW. I have a high pedal with lots of pressure but seem to be lacking the "bite" I know the Wilwoods should have. I should be able to go from 60 to 0 mph in under 120 ft. I'll continue to test our braking system. Stay tuned.
