It would be easy to assume that the ’92 Carrera Cup USA was a turned up version of the RS America, but actually it shared more DNA with the European market Carrera RS. Porsche intended to continue the trend of its successful 944 Cup and 944 Turbo Cup support series races with a 911 Carrera Cup in the U.S., but after luring 45 buyers and converting 25 to full race spec by Andial funding for the series fell through. Many of the Andial-converted cars were then returned to full road-legal spec and the legend of these lightweight 911s has been circulating ever since.
he RSA was actually the least expensive 911 version in showrooms in the early 90s too, while the Cup was a substantial 20% premium. Why? Well, it was a lot more than just removing a few extra items. While the RS America lopped 70-odd pounds off a standard C2, the Carrera Cup was 200 lbs lighter. The Cup wore bigger 24mm 5-way adjustable front/ 18mm 3-way rear sway bars, stiffer progressive-rate springs that were 50mm front/45mm rear lower than a standard car, aluminum hubs, ball joint upper spring mounts, and Bistein rear shocks. The engine was the M64/03 rather than the RS America’s M64/01, and featured a lightweight flywheel, only one accessory belt, a remapped DME and solid rubber mounts to channel more of the extra power to the ground. The Cups had a lightweight battery and master electrical shutoff, along with a more simple carpet and rear shelf layout. The gearbox was also different, as the Cup for the G50/10 with longer first and second gears, hardened synchros and mounts, and a standard variable locking differential. Brakes? Yep, different too – the Cup wore Turbo calipers with 322mm front vented and cross-drilled rotors. They kept the standard retracting rear spoiler rather than the RS America’s fixed unit, but had no undercoating and thin glass as well. These were racers through-and-through. And today, they’re not cheap:
