The Clubsport version was specially developed to enable the drvier of the 911 GT3 to participate in motorsport with the homologation required but without having to elaborately retrofit his car. Features include a roll cage bolted to the body as well as the absence of side airbags. The cage interacts with the spring strut supports on the rear axle in order to stabilise the car, with chassis and suspension forces being fed not only into the body, but also directly into the roll cage. Under tough motorsport conditions this means that forces acting on the rear spring struts cause only minimum deformation of the body. The rear axle geometry, in turn, is not influenced by these forces and ensures much more precise guidance of the rear wheels serving again to improve the driving characteristics of the 911 GT3 Clubsport.

Instead of leather, the bucket seats in the Clubsport version come in flame-resistant cloth upholstery. And apart from the use of red three-point seat belts the Clubsport model is also fitted with a red six-point seat belt on the driver's side not homologated for public roads in Germany as well as a fire extinguisher mounted on a separate support
