The advertised 60% increase in grip also increases pedal pressure very slightly, but it still engages quite nicely.

Racing Beat light steel flywheel

4.444 Ring & Pinion Gears

This '7 is set up for a road course, not the speedway! These gears, along with the slightly shorter than stock wheel/tire package I'm running, result in an engine speed of about 4000 rpm at 70 mph in fifth ge Acceleration in the lower gears is vastly improved, however. First and second gears go by in a flash when you're under full throttle.
