Home/Buyer's Guides/991.1 GT3 RS
The aero monster · 2015-2016Function dictates form: prices, weak points, technical checks and a checklist. So you can assess the history, the condition and any track use with confidence on site.
The Porsche 911 GT3 RS of the 991.1 series was more than just a faster GT3. It was a technological statement. While the "ordinary" 991.1 GT3 struggled with engine problems, in 2015 the RS introduced the completely new and extremely durable 4.0-litre naturally aspirated engine (MA1.76) engine.
Visually it broke taboos: the huge air outlets on the front wings (the louvres) and the gigantic rear wing showed that downforce came before aesthetics here. With the wide Turbo body, a magnesium roof and the obligatory PDK gearbox, it is today a sought-after collector car that bridges road and racetrack.

Magnesium & carbon
No manual gearbox was available. The seven-speed PDK was laid out as "PDK Sport" (PDK-S). Shorter ratios, a "paddle neutral" function (disengaging the clutch by pulling both paddles) and a pit speed button for the pit lane underline the motorsport focus.
The engine holds up, but the bodywork and suspension parts are costly.
Lightweight construction has its price. Check the bodywork meticulously.
The RS uses uniball bearings for maximum precision. But that also means more wear.
