so I am shopping around for a disk brake kit for a 63 Valiant and I notice Wilwood has four piston kits. They seem a bit fancy for what I am going to use the car for but with a coupon some of their kits are comparably priced to some other kits out there. So far the ram man seems to be the best value. Scarebird looks good but a lot of leg work to put it all together. any thoughts ?
