My mph goes down a bit when we race down there. Which hole did you use on the Relocaion brackets? Run the tires at 16lbs cold and see what it does with a good burnout.
The car has only been ran at OSW and the mph never fluctuated that much even with the weather changes. Tires were at 15.5 cold and it's in the middle hole.
The good thing is that the rear wasn't boucing around like it used too, friends say it squated and stayed.
