The package includes several upgrades to boost the car's performance. Manthey has replaced the rear window with a carbon fiber panel that's 25% lighter. This panel features a shark fin antenna, similar to the one on Porsche's 963 endurance racer.
On the roof, Manthey added six small fins. These help guide hot air from the front radiators. The rear wing got new endplates, and the diffuser grew larger. Both changes aim to increase downforce. Carbon fiber wheel covers round out the aerodynamic tweaks, cutting down on air resistance.
With all these changes, Manthey claims the car can produce over (1000kg) 2,204 pounds of downforce at 285 km/h (177 mph). That's a significant boost in performance.
But Manthey didn't stop at aerodynamics. They also stiffened the suspension, increasing spring rates by 30% in front and 15% in back. New shock absorbers are part of the package too. For cars with ceramic-composite brakes, Manthey offers racing brake pads.
The company added some cosmetic touches as well. These include body decals, illuminated carbon fiber door sill guards, and LED door projectors. There's also a towing eye, but it's not for use on public roads.
"We've spent two years developing this kit, testing it for thousands of miles on European racetracks," a Manthey spokesperson said.Manthey plans to take their modified GT3 RS to the Nürburgring for a hot lap. They're aiming to beat the standard GT3 RS time of 6:49.32, set in October 2022. They'll have to work hard to top the previous-gen 911 GT2 RS with Manthey Racing components, which lapped the track in 6:43.30 in June 2021.
Drivers in EU countries can get their hands on the kit starting in January. The rest of the world will have to wait until March. Manthey hasn't revealed pricing yet
Now Porsche gears up for some big releases. They launched an updated 911 GT3 last month, and a revised RS model should follow soon. There are also rumors that a 992-generation GT2 RS is in the works.
