Fronts are 14" 6 piston, rears are 13" 4 piston. My car is a 85 C4 Corvette based conversion. My kits numbers are 140-11919-D and 140-11920-D. Be careful if you want to go with 14" on the fronts as wheel clearance could be a problem. Wilwood has dimensional drawings posted on their website and I used that data to make poster board templates to check the clearance with. I've got 18" wheels and they had considerable room. If you had 17" or smaller I'd be very careful. In fact they say they won't work on smaller than 17" wheels. I originally planned hydra-boost brakes but I spoke last year at the PRI Show with a Wilwood designer and he strongly advised against it as he felt they wouldn't at all be necessary. I'm going to discuss with them more this year (next weekend) and try to get the master cylinder size and type nailed down. I've really liked hydra-boost brakes on the vehicles I've had them on so I'm still leaning in that direction.
