For what type of drag car? How fast is it in MPH at the finish line, how long is the track length and shut down area, and how much does the car weigh?

I have the same question. I blew my master cylinder out racing and I'm looking for something a bit more heavy duty. 72 Cuda 340 95 - 100 miles/hr 1/4 mile; not sure how long the shut down area is. It wasn't very long .. hence hard braking 3,000 lbs (maybe lighter - had no interior in it at the time

cab, what size bore rear calipers are you using ? I have no idea, they where on the car when I got it I can't remember if their four pistons or six pistons, I think the rotors are under 12.0 inch diameter. I replace the rears several years ago due to them being heat cracked a bunch so I can try and measure them. They are 11 1/4 O.D. The car is in the trailer at the race track, I think it has the same size four piston calipers on both ends, dual calipers on the rear end. It stops fine so far, hoping to turn it up this year
