Im currently running 13" Baer front setup with the T-4 caliper and running the mustang cobra single caliper out back with a 12" rotor. I have been looking around at masters and I really like the Dual master cylinder setup from CNC. But I cant stop debating what to do.I've been doing some research and I found quite a few guys that are using the dual master cylinders and really like it on their street car where as others are advocating its not safe. The 67 will primarily be a street car with some AUTO X time and a couple of track days here and there. was just curious to see what everyone is running?
