That's how I knew the specs of the OEM calipers of similar Fords, as I posted the caliper piston sizes before. I knew with my large custom brakes on my Explorer mail truck, I wanted a little more for the back also. That's when I discovered the 2003-10 Crown Vic had 1.9" pistons, while the Cobra had 1.5" pistons. I bought the CV brakes before thinking through how they could fit my truck. Thus it's a PITA for my truck to put those one, but it may not be so hard on the cars. The parking brake cable has to go into the back, in stock form it's at the top, which shouldn't interfere with the car's suspension parts. I haven't looked under my Mark VII, which you know has the exact same HO Mustang 8.8 rear. But note the CV pads are not really any bigger than the Mustang pads, or my Explorer rear pads. The rotor diameter and caliper piston size are the big factors.With the limiting factor on front brakes being the rear brakes, i always wondered if there was a easier way to upgrade the rear cobra brakes without resorting to the high dollar aftermarket kits.
For example what would it take to install a set of the 93 Cobra/87-88 tbird/93 taurus 42mm varga style calipers in place of the 38mm on the 11.65" rotor? If you could theoretically mount those calipers properly, i wonder how that would affect the bias when running the 13" rotor and ATS brembos. Would it be more favorable?
Again...just thinking out loud. I'll likely keep my brake setup just the way it is
Here's the new caliper I have to make a bracket for, for my mail truck. This is a Wilwood six pot 5.44 sqin. piston area model, with massive pads.
