I'm amazed at how easy it is to run a 10.6, just mash the pedal. If I do everything right I turn a 9.7 but launch and clutch engagement has to be perfect, can't nail the throttle in 1st gear, 2nd gear engagement has to be quick but smooth and get to nail the throttle if track conditions are good. The major difference is my ride is only 1790 lbs instead of 5000 lbs.
