Unless the StopTECH kit has 12 pistons, you are doing your math wrong.

The way to calculate the overall piston area on fixed caliper is to take the overall area on ONE SIDE only. I.E. You count only 3 pistons on the same side in a 6 piston set.

Don't ask me why. I don't know why. That's just how it is.
The hell I don't! LISTEN, KID! I've been hearing that crap ever since I was at UCLA. I'm out there busting my buns every night! Tell your old man to drag Walton and Lanier up and down the court for 48 minutes!
