4 piston calipers?
If not, I don't see how a 4 piston would help you. Is it just for looks or do you want stopping power?
Also keep in mind that in order to fit a 4 piston caliper you have to switch the rotor to one which is inset more to the inside. That's the only way to get the extra clearance you need. So a stock rotor is not going to work.
1. a big brake kit will not help much with 50-0, since the tire compunds are mostly responsible for that. From about 80 mph is where the big brakes really begin to perform serious assigned duty.
2. You cannot resurface the friction rings, unless you use race pads, and many shops will not accept the work and tell you to perform that work yourself. Stoptech has a programme with resurfacing their rotors, but once again you're on your own concerning labour.
3. Even if the rotor is set more inboard than the OEM configuration, the caliper may still be wide enough that either you need a wheel with a spoke design that it will fit, or use a spacer.
I say to read the stang killers sticky at the top of the fourm, perform a thread search, decide on a manufacturer, then contact the vendors and/or manufacturers for details.
If you're not going AX or RR and don't have the experience, then question yourself if you need big brakes.
