Thanks for the link to the AP drawing MarkTurbo. I'll see if I can find a similar pic for the Wilwood caliper, failing that I'll call Wilwood and ask them for the dimensions. I'm surprised you have lots of room with a 330mm discs under 16's. How does your caliper compare in size to a CP5100? The clearance between the spokes of my wheels and caliper face is minimal at best.
Trip- Thats good going. I need a 10mm spacer with my brakes and 17's!
MrGTiR- I think a few have AP's, I just hope they read this thread!
paz- I was told that the Brembos were a large caliper when buying my brakes. God knows how I would have faired had I bought Brembos with my wheels, either monster spacers or like you a change of wheel..
