* Without ballast dictated by Balance of Performance (BoP)

The suspension and brakes of the 991 GT3 R were tested at the VLN long distance race on the Nürburgring-Nordschleife on 17 October, 2015. The engine in the test car was the well-proven powerplant from predecessor models as the new DFI (Direct Fuel Injection) engine was undergoing test runs in Weissach and in the USA. Compared to the 997, the wheelbase is 3.3"/83 mm longer.

The 991 GT3 R became available from December 2015 for the 2016 racing season that had new FIA rules for GT cars. Despite the 2016 991.2 Carrera already launched, the 991 GT3 R customer racing cars retained the looks of the 991.1 generation (factory team did not use the GT3 R).

The body panels of the 991 GT3 R are naturally made of carbon-fibre reinforced plastic (CFRP). All windows are made of polycarbonate and starting with the 991 GT3 R, also the windscreen. In accordance with the new FIA safety rules, the door windows are removable in addition to the slightly larger escape hatch in the roof. The doors are also removable. The engine is the same as in the street legal 991 GT3 RS, except the air for the engine is taken through the openings on the rear lid (the useless "show-off" side air intakes seen on the 991 GT3 RS are not used on the real racing car). The 120 litre FT3 cell has fuel cut off safety valve in accordance with FIA regulations. Like with the earlier racing versions, the air jack system with four jacks has been built into the car. The bucket seat can be adjusted fore/aft. The seat has adjustable padding system to suit individual drivers. With drivers under 80 kg, ballast has to be installed in the car.

2016 FIA GT World Cup

On November 19-20, 2016, a racing event called Macau Grand Prix was held and a once-in-a-year FIA GT World Cup event within it. A pre-race comment from Porsche driver Kévin Estre (911 GT3 R #912): “The street circuit in Macau is one of my top 3 racetracks – it’s very fast and incredibly difficult, with many bumps and blind corners. There are no run-off areas, only walls and guard rails. You have to focus from start to finish and you can’t afford to make the slightest mistake. The many fans lend a great atmosphere. For the majority of drivers it’s the last race of the year, so they’ll be doing everything to head into the winter break with a victory under their belts.”

The Macau Grand Prix hosted the TCR International, three local (Macau/Chinese) series and 2 FIA races (GT and F3). The Macau street track is narrow, slippery and has no run-off areas, so the accidents happened all weekend long. The most spectacular crash happened during the FIA GT World Cup race when a second place Audi R8 landed on its roof. The GT race was terminated after this incident. Although the race was supposed to be 18 laps long, with many accidents only 1 or 2 timed laps could be counted. At the moment when the race was terminated, two Porsche 991 GT3 R were leading (1. Earl Bamber #911, 2. Kevin Estre #912). According to the rules the positions of the last full lap were accounted for the race and it meant that Laurens Vanthoor who landed his Audi R8 on the roof, was named as the winner of the race (Porsche didn't bother to make a scene out of the situation as Vanthoor was already contracted to be a Porsche factory driver from next season). In addition to Earl Bamber not winning, he also got a time penalty for dangerous take-over. The take over was perfecty perfect, so the stewards must have had their nervs fully eaten up as the flying Audi was around 50th (!!!) car that crashed into the guardrails during this weekend. More crashes followed in the last race of the day, the Formula 3 World Cup.

Anything can happen here and it usually does." True, true.© Porsche
