As the 919 Hybrid was not made available for customer racing teams, the RS Spyder was the last mid-engined racing car that Porsche offered to its customers - until the 2016 Cayman GT4 CS.

The car is confusingly named as the GT4 Clubsport. Clubsport versions were always street legal, but not the GT4 CS. The difference between professional racing and amateur club racing was that you could drive your racer to the club sport events and back home.

The 981 GT4 racing version has the same 911 3.8-litre 283 kW engine as the street legal GT4. The racing version GT4 was available only with a unique 6-speed PDK automatic gearbox and was solely destined for private racing drivers (Porsche works teams use sequential gearboxes for racing). The suspension was adapted from the 911 991 GT3 Cup car. The size of the standard fuel tank was 90 litres. FIA-approved FT3 tanks were optionally available in 70- and 100-litre sizes. Although the 18" wheels and tyres of the racing GT4 were much lighter than the 20" units on the street version, at 1300 kg/2866 lb, the stripped out racing version is only 40 kg/88 lb lighter than the street legal version because of the full rollcage and heavier automatic gearbox. Like all racing Porsches, the racing version of the GT4 is a Porsche Motorsport product (not available from Porsche dealers).
