In 1981 Porsche released the limited production 924 Carrera GTS. 59 GTS models were built, all in left hand drive, with 15 of the 59 being raced prepped Clubsport versions. The Carrera GTS differed stylistically from the GT with fixed headlamps under Perspex covers (instead of the GT's pop up units). GTS models were also 59 kg (130 lb) lighter than their GT counterparts at 1,121 kg (2,471 lb), and Clubsport versions were even lighter at 1,060 kg (2,337 lb).
