??? brake converstion
I agree that the kits that are just stock GM single pistons are no gain over a stock Mopar single piston setup. Those Kit companies use GM or Ford mustang calipers because they can get them cheaper because the parts have more volume. AND they use GM/Ford stuff because those companies started off making GM and Ford conversions and they can have economies of scale by sharing parts over various kits for different brands.
People feel gains from them because they are coming from a drum brake setup.
Even the Willwood 4 piston conversion kit or the Willwood 4 piston caliper on a Mopar rotor is not a big gainer. The big deal with the wilwood kit is that it's lighter than stock. It was devoloped for drag racers.
You go to a AR Engineering Viper caliper conversion you've got a pad with a more surface area and you have a caliper that will not flex and keep the pad flat on the rotor. Same for the Willwood big caliper 6 piston 13" rotor kit.
Mine stops good on the street: junkyard 11.75 Mopar conversion, Mopar police semi metalic pads, MP aluminum master, steel braided flex lines, DOT4 high boiling point fluid.
At the track you can reach the limits with 11.75 on a 3350 lbs car. But you can cook any brakes if you just abuse them incorrectly and don't try to be smooth. I just drive conservative with the brakes. I was especially carefull at Buttonwillow which is a track they all said was tougher on brakes. They got sort of spongy. I still went out and ran more, but it was enough to notice for sure.
I know brake ducts would make a huge difference. Need to make some. I got a good deal on some hose. And I've got some used diffusers. Too bad one is 2" and the other is 3" #-o
