    Rated 3 out of 5 by from Nothing Special Weights and cam are 'cookie cutter' copies of every other aftermarket advance kit out there. Springs are the only part that varies a little. Instructions are pretty poor, there are a couple of non-flanged bushings in the kit and it isn't evident at all how or where they are used.
