Todd I can leg press 1200lbs (like a boss) yeah ill have to call Tobin on monday and see what he has to say Ill start running the math and compare notes with Tobin.

Im just worried because there IS 20 pistons yet maybe small but im thinking the 1.125" bore will help with the pressure I could be wrong.

edit: C6 Z06 brakes require 1600psi (says the internet) so I whipped out the scientific calculator and got down to buisness

Based on 150lbs pedal force.
7/8" bore 1600 PSI - Force on prop rod 960lbs - pedal ratio 6.4:1
1" bore 1600 PSI - Force on prop rod 1264lbs - pedal ratio 8.43:1
1 1/8" bore 1600 PSI - Force on prop rod 1585lbs -pedal ratio 10.56:1

Well then.. Looks like ill need a 7/8" bore master cylinder since my Stock pedal ratio on the Sonoma is 7:1 so in my stated above I was wrong.. 7/8" I guess is what I'll be going with.
