Porsche 911 GT2 RS Clubsport 991 Evo kit increases aero efficiency for racing

The 991 GT2 RS Clubsport can be fielded at clubsport events, track days and in GT2 racing series. Now, thanks to a new factory Evo kit, the twin-turbocharged track attacker has become even more formidable.

Porsche’s priority was to increase aerodynamic efficiency, thereby ensuring a more consistent performance over long distances. The update primarily includes redesigned eighteen-inch wheels, modified shock absorbers and improved safety features. The underlying technology of the host 911 remains unchanged, meaning continued use of a twin-turbocharged 3.8-litre flat-six.

“With the introduction of the 991 GT2 RS Clubsport back in 2019, Porsche was a trailblazer in the revival of motorsport’s GT2 class,” explains Michael Dreiser, Director of Sales at Porsche Motorsport. “We continue to see positive development in this category and want to give our customers the means to carry on competing with their 911s at the top of the GT2 sector, which they’ll be able to do with this new 991 GT2 RS Clubsport Evo kit.”

Extensively revised aerodynamics is the key component of the package. The front section features a new apron with modified air intakes for brake cooling, the diffuser and centrally-mounted radiator. The front lid has been adapted to provide greater ventilation. A redesigned front splitter generates more downforce on the front axle. In combination with the new and higher Gurney flap on the rear wing, the overall aerodynamic balance of the GT2 RS Clubsport has improved greatly.

The Evo kit brings the car’s competitiveness up to current standards, especially in endurance racing. In competition use, the kit was deployed for the first time when Ebimotors and Manthey- Racing contested the European Fanatec GT2 Series in Monza, Italy, not long before this issue of 911 & Porsche World went to print. An exemplary race from last year’s third-place Am championship winner, Leonardo Gorini, assured the no.911 Ebimotors GT2 RS Clubsport fifth overall and second in the Am class in the first race of the weekend. Aurelijus Rusteika and Mantas Janavicius drove the no.5 Ebimotors Porsche home in eighth overall, thereby rounding out the Am class podium. Unfortunately, Manthey-Racing’s lone 911 was forced to retire after being run off the race track by a competitor.

SECOND TIME LUCKY

Better luck for race two, when Christoph Breuer scored his first Am podium in the Manthey- Racing 911, taking third in class. Meanwhile, Rusteika fought hard to secure second in class, once again proving the new Evo kit’s competitiveness in the heat of battle.

Broadening the front and rear quarters has created more space for wider rims. These have now grown from 10.5 to twelve inches at the front axle and from 12.5 to thirteen inches at the rear. Also, thanks to the modified dampers, tyre wear has been reduced. Newly designed side skirts serve to add visual coherence to the package.

Significantly larger air outlets in the rear apron offer more efficient ventilation of the back brakes and the engine compartment. This reduces thermal load on the components, a concern when racing in summer. An SRO GT2-approved safety package includes a quick-fill fuel system and reinforced side impact padding.
