SouthernFried - I would think the big difference in race/street would be about $15K...Race setup would have big brakes, different suspension that wouldn't be fun on the street, fuel cell, a motor that'll buzz to 7000 all day long, full roll cage, tubbed interior, aluminum flywheel, the list can go on and on and on...Basically a race prepared GT-350R would not be fun on the street, and the loud pedal would get your butt thrown in the clink...
...hey, that ryhmed.
