The 2008 model year marked the first time the S2000 was offered in more than one trim level in the United States. In addition to the base model, Honda offered a more track-oriented version of the S2000, distinguished by reduced weight, fewer amenities, and an increase in performance. The S2000 Club Racer made its world debut at the New York International Auto Show on 4 April 2007. Changes for the CR included a lower ratio steering rack, revised exhaust system, black lug nuts, darker colored wheels, clear side markers, stiffer suspension and new Bridgestone Potenza RE070 tyres that were 10mm wider at the rear (255/40R-17 vice the base model's 245/40R-17). A revised body kit, composed of a redesigned front lip, and a large spoiler, were wind-tunnel tested and claimed to reduce the overall coefficient of lift by 70–80%. The power folding soft top was removed and replaced with a Berlina Black hard top (regardless of the car's body paint colour), while the space into which the soft top would normally fold when lowered was filled with additional chassis bracing and topped off with a body-color tonneau cover. Honda also used a CR-unique yellow-lettered spherical aluminum shift knob which rests 12.6 mm lower than the base model's cylindrical shift knob (aluminum/leather wrapped). The CR knob provided a 6 percent reduction in shift stroke, and correspondingly presented a 10 percent higher shift load effort.
