Mitch, you're funny. EMPI is a problem. They are SLOWLY getting better. I think we'll all be dead before they are the best though.
Did you guys know I had to do some machining on the Airkewld 4 piston fronts that I paid a LOT for($2200 or so for front and rear)? The grease seal(supplied by them) wouldn't fit in the hub, I had to open up the seating hole in the hub. I also had to machine down the outer snout so a stock grease cap would fit. I made them a slip fit, and secure the caps with a schmeer of silicone. That way I don't mar up the polished aluminum when taking the caps off. Miraculously, the rears only required sanding the e-brake circlip thinner so it actually fit in the slot in the cable. The rear brake assemblies themselves slid right on, no problems.
I don't think one single part on my car hasn't required massaging/modification of some sort. Except JayCee parts, they fit. But the company was just purchased by EMPI, so now who knows?
