Thanks again for all the replies guys. Your comments bring up a couple of other questions:

1. For those of you using the ABS front brakes; did you switch from the non-ABS setup, and if so did you notice a big difference in stopping? I've thought more than once about switching, but when it comes time to order new pads/rotors I always seem to go the easy route - I mean heck, the car stops pretty darn well with the smaller setup, and there is only 5mm difference after all. By my calculations that's about 2 square cm difference.

2. I've asked this in previous threads, but it might be worth bringing up again - those of you running blues on both ends; are you using proportioning valves? I use the HP+ pads on the rear, and find that I still always lock up the rears first. Part of my problem may be that I haven't gotten around to installing ducts yet, but on tracks like Summit and VIR where there are only 2 - 3 hard braking zones that shouldn't be as big a problem, should it?
