SCCA ITS Record (~185 wheel hp, stock suspension, aftermarket coilovers, Hoosier DOT Rs) is 1:37!!!! Set last year by Huffmaster (can't remember his first name but he rented a car from us years ago, nice guy) in a 2nd generation Mazda RX7. People make fun of our old jalopies but some of them do well. A "normal" ITS time falls in the 1:39-1:41 range, again with 170-180 rear wheel hp.
