Paul, while you are changing calipers, also try to dial up the correct caliper piston sizing to keep the correct front to rear brake bias. I'm currently changing calipers to correct my brake bias. Doesn't help you as I have larger aftermarket rotors on my Jag front end, so my caliper choices won't be applicable.

Wilwoods are particularly good in this regard as you get a good choice of piston sizes.
