The Willwood spacers are .030". The calipers are spaced as close to center as you can get within .030". The pad wear is square to the rotor. The other day when we talked, the Willwood tech he made no mention of using round caliper seals. I wonder why? He also has not returned my E-Mail since. Its been 5 days. The area outside of the seal was relieved and polished along with the pistons. Now at least you can move the rotor by grabbing the wheel studs. It doesn't spin but at least it moves. Waiting on the shocks. So we'll see when its on the ground.
