The Porsche 997 GT3 RSR was the ultimate 911 developed for GT2-class racing, homologated for ACO, FIA, and IMSA competition. Introduced in 2007, it was heavily revised for 2008 to improve reliability, handling, and aerodynamics – essential for it to remain competitive against Ferrari, Corvette, and others. Key updates included a new six-speed sequential gearbox, along with revised suspension geometry, a flatter driveshaft angle, and Sachs four-way dampers for improved tuning. The front-end aero was also upgraded with dive planes, refined ducting, and underbody changes to increase downforce and reduce drag. Its 3.8-liter flat-six remained largely unchanged, producing 465 hp at 8,500 rpm and 317 lbs./ft. of torque at 7,250 rpm, with dry sump lubrication and a forward engine placement for better balance. The 2008 RSR featured a seam-welded shell, carbon bodywork, integrated roll cage, and MoTeC electronics. Campaigned by top privateers like Flying Lizard and Felbermayr-Proton, it earned major wins at Sebring, Le Mans, and Spa, reinforcing Porsche’s dominance in GT endurance racing.
This Porsche 997 GT3 RSR, chassis 799921, is one of 35 examples built for the 2008 model year. Finished in Carrara White, it was originally delivered to the Madrid, Spain-based DriveX Motorsport team, founded in 2003 by GT champion Miguel Ángel de Castro, former Formula 1 driver Pedro Martínez de la Rosa, and collector Jaime Bergel.
Primarily driven by Miguel Ángel de Castro, with co-drivers including Miguel Amaral and Antonio Chacón, this RSR was actively campaigned in the Spanish GT Championship and International GT Open series. Highlights from 2008 include a pair of podium finishes, with 3rd place results at Jerez and Albacete, as well as top-five finishes at Jarama. The following year, the RSR continued to show strong form, taking 2nd in Race 1 at Valencia and finishing 4th in Race 2. The RSR continued to be campaigned in the GT Open series by the team through 2014.
This RSR was later acquired by American GT racer Alex Welch, a Pirelli World Challenge GTS-X champion with extensive experience in GT3, GT4, and Porsche Cup racing, as well as endurance events like Sebring. It was more recently purchased by its current owner, an accomplished amateur driver with starts at Le Mans, Daytona, Sebring, and Spa, frequently competing with top-tier GT teams. Today, the car presents as a well-prepared example with documented race history and recent mechanical attention. The 3.8-liter flat-six has recently been serviced by Porsche Motorsport North America and is reported by the consignor to be in proper running order. Accompanied by its manuals, logbook, and a selection of spares, this 997 RSR offers a compelling opportunity for further preparation and use in historic endurance events, or as a significant piece in any motor sports-focused Porsche collection.
