Track-only Porsche 911 GT2 RS Clubsport 25 unleashed

Porsche and German motorsport team Manthey Racing have pulled the drapes off a new Porsche 911 GT2 Clubsport 25 created for wealthy track day fans.

Built to commemorate their partnership over the past 25 years, the new limited-run track-only 911 is based on the 991-generation Porsche 911 GT2 RS Clubsport.

Priced from an eye-watering €525,000 ($A840,000) plus taxes, just 30 of the heavily modified 911 GT2s will be made and all come with the upgraded 3.8-litre flat six-cylinder twin-turbo that made its debut under the rear boot lid of the Porsche 935 that was unveiled back in 2018.

Like the 935, the Porsche 911 GT2 RS Clubsport 25 produces 515kW to the rear wheels via a seven-speed PDK dual-clutch transmission.

Ensuring it's cut out for track work, both Porsche and Manthey have made extensive tweaks to the GT2, including adding a revised centrally positioned radiator that provides better cooling for flat-out driving over long distances. The new rad is said to not only perform better but is less prone to damage.

Featuring a significant aero rethink, there are new front winglets for better downforce while the undercarriage is now completely enclosed for optimum air-bending.

Other changes include a new front bumper that incorporates a huge splitter and a deeply sculptured bonnet and wider wheel-arch extractors. That bonnet vents hot dense air from the radiator that is said to be channelled over the body and directed to the rear wing, boosting downforce.

At the rear-end there's an enormous spoiler that's fixed to the car using swan-neck mounts, plus an extended boot lip that sits above a motorsport-grade diffuser.

Finally, large vents ahead of the rear wheels jet cool air to both the engine bay and brakes.

Other highlights of the track-bred GT2 include a pair of headlights inspired by the Le Mans-winning 911 RSR Manthey campaign that are claimed to be specially developed for track work.

Sporting ultra-lightweight 18-inch alloy centre-lock rims, the GT2 Clubsport 25 runs the same track-focused suspension as the 935, which uses a wider track for higher grip.

Within the cabin there's said to be a full welded-in safety cage that complies with FIA standards.

The grey and lime colour combination is another nod to a Manthey-winning Porsche, paying tribute to this year's winner of the Nurburgring 24 Hours race.

Manthey and Porsche's close working relationship dates back to 1996 when the race team was founded by Olaf Manthey. The German car-maker bought a majority 51 per cent share of the race team back in 2013.

That explains why Manthey now develops MR packs for both owners of the 911 GT2 RS and the 911 GT3 for those who use regularly track their car.

Currently, a Manthey-tuned Porsche 911 GT2 RS holds the production car lap record at the Nurburgring with a time of 6:43.3.
