I was talking to Russell about the Wilwoods and he said he literally has beaten the hell out of them on the track several times over 2 years and has not had to rebuild them. With the limited amount I drive my car, that may not be an issue. But I'm very interested in seeing results of your kit. You definitely have my interest. It's coming down to the wire on making a decision on a kit. You both have good stuff! So many decisions...
