James, I'm not spacing the fronts. Not enough call for it. Excellent idea though. Mike should engineer some spacers to sell with the Mueller hubs (ooooooooooops, is Brad reading this?). They should be 7mm I believe.

Josh has nailed it from what I can see. If you're going to do more of these then the M-Caliper would be the ticket. The pad size is the same. The only advantage is the vented rotors in my book.

There's a guy here on the PP 911 boards that makes -6 shrouds. He also makes some very nice A-arm ducts. The ARJ kit may be all that's needed (along with the nice pads and fluid). No need to cut the front.

I'd say the bottom line is based upon how many track days vs. autocross days this car will be seeing. Air, pads and fluid will probably get you by for now.
