The birth of a legend · 1999-2006The founding father of the track tools: prices, weak points, technical checks and buying checklist. So you can verify originality and avoid expensive mistakes.
The Porsche 911 (996) GT3 marks a milestone in the history of Porsche road-going sports cars. As the very first GT3, it laid the foundation for a model line that is coveted by enthusiasts and collectors alike to this day. With its motorsport-derived Mezger engine and its purist focus on driving dynamics, the 996 GT3 represents the perfect connection between road sports car and race car.
The 996 GT3 was offered in two generations: as the MK1 (1999-2001) and the MK2 (2003-2005). Alongside them came the even more exclusive GT3 RS, which added further lightweight measures and a specification close to motorsport. This buyer's guide gives prospective buyers a comprehensive overview of the technical particularities, the possible weak points and the important buying criteria.

The Mezger engine is the heart of the car. Here is everything about it.
A technical masterpiece: The heart of every 996 GT3 is the legendary Mezger engine. Unlike the regular 996 engines, which struggle with the IMS problem, the GT3 engine is based on the motorsport architecture of the GT1 race car.
The GT3 is reliable, but track use leaves its traces.
Engine and drivetrain:
Suspension and body:
The suspension was developed for the racetrack. The MK1 is lowered by 30 mm, and on the MK2 the suspension was optimised further. The RS has adjustable dampers and a carbon bonnet.
250 to 600 pages of expert knowledge (depending on the edition) as a model-specific basis for your decision on the 996 GT3 and GT3 RS: detailed weak points, engine codes, specification details, inspection checklists, production figures, value-enhancing options and price forecasts.
