I have Wilwood 12.88" disk. 6 piston front and 4 piston rear with the drum parking brake. When I called them they set me up with an engineer and we worked out what it was going in and how I was going to use it right down to the weight of the truck. They then put together a custom package from the master cylinder to the pads. I was lucky enough to get the Nickle plated calipers for the short period of time they offered them. I was having my Frankland quick change built at the time and they called Frankland to get the width and flange right for their brakes. I like all my parts in a system to be the same supplier if possible. After all that they said if you buy it from summit they will be less money than from us. I asked them why and they said "they sell a lot of brakes". It saved me about $650. I have a 53 3100.
