Porsche 911 GT3 RS Manthey Upgrade: Shark Fin, Big Downforce, and Track-Ready Tweaks
The Porsche 911 GT3 RS has always been a monster on the track, but Manthey Racing’s latest factory-backed upgrade kit cranks it up to a whole new level. With cutting-edge aerodynamics, suspension tweaks, and enough carbon fiber to make a Formula 1 team jealous, this upgrade isn’t just a style statement—it’s built for serious performance. Let’s take a closer look at what makes this package so special.
Goodbye Rear Window, Hello Shark Fin
Let’s start with the elephant—or should we say, shark—in the room. The rear window is gone, replaced by a lightweight carbon fiber panel with a shark fin antenna. This isn’t just about looking cool (though it does look cool); it’s a nod to Porsche’s 963 endurance racer. The fin and six smaller roof fins help direct hot air away from the rear intakes, giving the engine a steady stream of cooler air to keep it breathing easy during those high-speed laps.
Manthey didn’t stop there. The massive carbon rear wing got a makeover with new endplates for even more downforce, and the diffuser is bigger to improve airflow. Add in carbon fiber aerodisc wheel covers to reduce drag, and you’ve got a car generating over 2,204 pounds of downforce at 177 mph. That’s serious stickiness on the track.
Tweaks Where It Counts
This upgrade isn’t just about the exterior; Manthey dove under the surface to fine-tune the GT3 RS’s suspension and handling. Up front, the spring rates are up by 30%, and the rear gets a 15% boost. The new shock absorbers are built to handle the demands of racing, and for those with ceramic-composite brakes, the package includes racing brake pads for sharper stopping power.
This setup wasn’t thrown together overnight. Manthey spent two years and countless miles of testing across Europe’s toughest racetracks to get everything just right. So, if you’re hitting the track, this setup is ready to work as hard as you are.
A Few Extra Goodies
Of course, no Manthey kit is complete without a few bonus features for Porsche lovers. You’ll find illuminated carbon fiber door sill guards, LED door projectors, and even a dedicated towing eye (though it’s strictly for track use). These are the little touches that show this car isn’t just about numbers—it’s about passion.
Lap Times, Anyone?
Speaking of passion, Manthey has plans to set a hot lap at the Nürburgring. The goal? To beat the GT3 RS’s already-impressive lap time of 6:49.32. Weather hasn’t been cooperating, but when the stars align, don’t be surprised if Manthey shaves off a few seconds.
When Can You Get It?
If you’re lucky enough to own a GT3 RS, the Manthey kit is available for order now. Deliveries start in January for Europe, and non-EU regions will have to wait until March. Pricing hasn’t been officially announced, but considering the kit for the 718 Cayman GT4 RS runs $53,946 plus installation, you can bet this one will be in the same ballpark.
Whether you’re chasing lap times or just want your GT3 RS to look like it rolled straight out of a Porsche endurance race, this Manthey upgrade is the ultimate flex. It’s proof that even one of the world’s best track cars can get better with the right team and a little bit of carbon fiber magic.
