It will be interesting to see a comparison test between the BBK kits and the stock brakes.... I think the standard 60-70-80 to zero test only once....there won't be much of a difference....only on the track after repeated hard braking will the BBK's start to show improvement over the stock brakes...but for a street car....its not worth it.... but the BBK's sure look better!
