Will your next step be the 125cc road course jobs? (0 to oh my god in about 50 feet, 4 wheel discs w/driver controlled proportioning or better yet, a handbrake for the front and pedal for the rear
)
If you ever get down to Florida, (Daytona area I think), there's an 'experimental' (so far unsactioned AFAIK) class they've been working on for a couple three years now for one of the big sanctioning bodies:
500cc 6 or 7 speed liquid cooled road course class.
Those things will literally pull the front tires off the track coming out of the slower corners.
