Just for giggles, I attached two worksheets showing a wide range of different front brake calipers. The Superlites are model NSL6P ... which stand for Narrow Super Lite 6 Piston.
The TOP CHART shows all the calipers with the same brake pads, pedal ratio, master cylinder, input, etc, as I outlined for your car. Go look at the different braking force numbers.
The BOTTOM CHART shows the brake pads, pedal ratio, master cylinder, input, etc ... that we would run with the Superlite Caliper in Short Oval Track racing in a 2900# Late Model Stock Car. Now ... go look at those different braking force numbers.
You'll notice the Dynapro 6 I suggested ... has more braking force with a 13" rotor ... than the Superlite has with a 14" rotor.
Clamping force by itself doesn't mean a particular caliper is good or bad. Just realize, when you put a brake system together ... EVERY detail matters. I like the Superlite caliper for running 2900# short track stock cars. But you need to design the whole system to achieve the desired braking. My opinion is the pistons are on the small side for 3500# PT street cars ... requiring a aggressive race pads to achieve the optimum braking numbers. Aggressive race pads wear out quicker & cost more.
HEY GUYS following along with this thread ... Please do not just "Run with these Numbers" for your brake system.
I posted these for our discussion only. Getting a brake system designed correctly for your car is one of the most important things you need to do. If you have questions ... please ask. I'm happy to offer information, guidance & calcs to help you in your decision.
