I am at the pont now in my project to get a new master cylinder. I am running c4 dual calipers in the front and lt1 in the rear. What I would like to know are people using the stock 3rd gen booster and master cylinder or are the upgrading to a 4th gen ?

 

I have an 82 w 13.5 inch wilwood 6 pistons up front and 4 pistons in the rear w a new 82 4 wheel disk master and a wilwood adjustable prop valve. It's awesome. The car stops scary fast. No issues w the MC. I thought about a 4th gen Mc and was talked out of it by Tobin at kore3. I'm glad I kept the stock MC.

 

Good deal. I am glad that I asked before spending all that money.
