i dunno, id say 30ish, its a tight course, they'll keep pulling in the straights if you didnt have to brake. they spin out, they understeer, they drift, they are quite realistic i'd say.

the comp cart is the best, i havent seen it out in a while though...it has 4 wheel disc brakes, and itll smoke the tires down the straights and spin you easy as hell in turns. on the old track, when i was consistantly running low low 21's, it was a 18second cart with a crappy driver.
