The Clubsport was up to 100 kg (220 lb) lighter and became available in 1988. This model was the toned-down version of the 1987 factory prototype which had a lightened body. In 1987, the factory made five white lightweight S4 models with a manual transmission for racecar drivers. The Special Equipment (SE) was a more complete version of the CS, in which some accessories lost in the CS are added back again.
