9 seconds on 9 inches???

At your weight it's not hard to do what your looking to do. IF your stuck on leafs you can by a set up or make something that will work well for less,$$$,but will still require tuning as do Caltracs. I'd go Assasins if I was stuck on leafs. Ladder bars or 4 link can stick in a blizzard and are far better if you race many tracks and conditions. Period!
