I'm kicking a few emails back and fourth with Wilwood to find a good caliper for the rotor. GT, thanks for the offer but I'll probably borrow a wheel from Mike when I get to that point as he's closer. Mike, In the next three weeks, I should have some pretty stoudt brakes to assemble on one of my Rockwells and I'll test the calipers I get with that to see if they'll work. I want this to be basically as simple as possible and as bolt on as possible. I'm happy with the rotor I found, although it will need a little trimming on it's overall diameter to work with a 16" wheel. 15" is out with this set up so far. The same rotor will work front or rear. The plate wheel will be much more simple because of the flat center, but if I get them to work with a stock wheel...they'll work with them all. I'll keep you guys posted...one of ya may volunteer for some testing for me too.
