What D-Cel (Jason) said. Although I seem to recall some staggered bore 4 pistons as well. Either way, Wilwood is the best bargain in performance brakes today and their full disclosure of technical data such as the temp vs cf charts on their pads make it, at least for me, my first stop if I am designing a brake system for some one. My oldie but goodie Unique uses an MG front end and the wilwoods don't fit... at least until I was done machining their hubs they didn't. It was worth the time. The difference from the Girlings is nothing short of miraculous.

Jason... did you ever get my brake work sheet? It is in Excel and you can enter all the paramaters (everything from aero CG's and specs down to tire CF) and play with the combinations on paper before you try it in real life. You would probably have fun playing with it. Email me and I will send you a copy. Also, The wilwood kit I modified to fit the MG spindles was a 70 chevy mid size kit as I recall with 10.75 rotors. I want to change those out for the 12.19 so I will be in touch!
