The 997 GT3 RSR was the privateer GT2/GTE weapon of its era: Weissach's customer flagship from 2007 to 2013, it won its class at Le Mans, swept ALMS titles with Flying Lizard and remains the most usable of the classic RSRs.

## History

Porsche built the 997 GT3 RSR as the customer counterpart to its factory efforts: based on the 997 GT3 RS shell with the Mezger 3.8 (later 4.0) flat-six, sequential six-speed and wide GT2-class aero, sold and supported worldwide through Porsche Motorsport. Annual evolution kits — aero, engine steps to 4.0 litres, driveline — kept the car current across seven seasons, and over 60 chassis were built, an enormous run for a GTE-class machine.

Its record is the definition of privateer depth: Le Mans GT2 class victory in 2010 (Felbermayr-Proton) and 2013's GTE-Am win (IMSA Performance), American Le Mans Series GT2 championships with Flying Lizard Motorsports, FIA GT2 European titles, Sebring and Petit Le Mans class wins, and Nürburgring/Spa 24-hour campaigns — usually against factory-backed Ferraris and Corvettes.

Today the 997 RSR occupies the sweet spot of the classic-GTE market: young enough for parts (Mezger specialists abound), old enough for the historic GTE/Endurance Legends grids now booming, and mechanically the most owner-runnable of the RSR line — no factory-controlled hybrid-era electronics, just a superbly documented customer race car.

## Palmarès

Le Mans class winner 2010 (GT2, Felbermayr-Proton) and 2013 (GTE-Am, IMSA Performance); ALMS GT2 championships 2009–2010 era with Flying Lizard; FIA GT2 European Championship titles; class wins at Sebring, Petit Le Mans and the Spa 24 Hours; Intercontinental Le Mans Cup GTE silverware — the deepest privateer trophy haul of its class generation.

## What to check before you buy

Chassis provenance through Porsche Motorsport is straightforward — build sheets exist for every car, and evolution-kit status (3.8 vs 4.0, aero year) defines both value and Endurance Legends eligibility. The Mezger engine is the cost centre: rebuild hours documented by a recognized specialist are the negotiation baseline, and 4.0 cars command the premium. Check the sequential box's dog wear, front-end crash repairs against the file, and completeness of the correct-year bodywork. Le Mans class-winning or podium chassis have crossed into collector pricing; 'ordinary' RSRs remain the best value in classic GTE.

## Did you know

- Flying Lizard's green-and-orange RSRs became so recognizable that Porsche later sold a road GT3 RS in tribute colours.
- The RSR's Mezger flat-six traces directly to the 911 GT1 and 962 architecture — customers were racing Le Mans-winning engine DNA.
- Over 60 997 RSRs built makes it the most numerous GTE-class Porsche ever — why it now anchors historic GTE grids the way 962s anchor Group C.
