Cheers mate that's the answer I'm looking for!
The rears are actually 6600 size so had toyed with just fitting them to the fronts with the 350mm discs if there was no point fitting them like you have said plus it's a road car?!!
370mm fronts would be nice but bit overkill?!
Failing that what would be a good caliper to use instead?!
Btw had the revolutions I got off you painted not so long ago do look rather nice!!
