Stole below from Trackmustangsonline. Would be cool to make it a sticky after a bit more info.
Looking for caliper size for pre/post either coyote and/or 2010, S197's (I think they went to twin piston at some point, correct?). Also, is MC diameter the same with all S197's, or did early one's get something smaller than 11-14?
I also want to add S550 stock 4 pistons. They are huge and kind of a bad option due to fit, but still want to put info up.
Caliper Piston Diameters inches (mm)
Caliper Piston Area (one side of caliper)
Master Cylinder Diameter
