Porsche 911 GT3 RS with Manthey Racing Kit

The kit beefs up the already colossal rear wing along with suspension and brake enhancements, solidifying the 911 GT3 RS as the ultimate track machine.

The Porsche 911 GT3 RS now comes with a Manthey Racing upgrade, boosting its downforce to over 2200 pounds at 177 mph. The kit includes a new rear wing with a shark fin, a redesigned front spoiler, and a more efficient rear diffuser. To handle the extra downforce, the spring rates have been tweaked, and the brakes are upgraded for even better performance.

The Porsche 911 GT3 RS already had one of the most massive rear wings on the market, but with the new Manthey Racing kit, it’s pushing aerodynamic performance into a whole new league. The upgrade ramps up downforce and sharpens the car’s track-ready edge—making it even more of a monster on the road or track. And the best part? You can get this high-performance kit straight from Porsche dealerships, and it won’t void your factory warranty. Pure track dominance, with peace of mind.

The rear wing on the 911 GT3 RS gets a major upgrade with a new split carbon-fiber DRS element and larger reshaped end plates, boosting downforce even more. A carbon-fiber shark fin, inspired by the Porsche 963 race car, sits atop a 25% lighter panel, improving cornering stability. This fin also helps direct hot air from the front radiator over the roof, keeping the engine intake cooler. Plus, the rear diffuser is wider with longer carbon-fiber fins, adding downforce without creating extra drag. It’s all about squeezing more performance from the car, with smart aero tweaks.

Up front, the Porsche 911 GT3 RS gets a serious aerodynamic upgrade with a reprofiled spoiler lip, carbon-fiber reinforcements, and restyled Gurney flaps on the wheel arches. Add in two dive planes ahead of the front wheels, and you’ve got a setup that cranks up the front axle’s downforce. To further minimize drag, Manthey has fitted carbon-fiber “aerodisc” wheel covers.

All these upgrades work together to push the 911 GT3 RS to an astonishing 2204 pounds of downforce at 177 mph. To handle that extra grip, Manthey also tweaked the suspension, stiffening the front springs by 30% and the rears by 15%. This track-focused package means serious performance—on both the straights and the corners.

Manthey has taken the 911 GT3 RS’s suspension to the next level with a new control unit and four wheel- and three body-acceleration sensors, making the automatic damper tuning more responsive and precise than ever. The dampers now feature separate valves for compression and rebound, each independently controlled for a more refined ride. With three drive modes—Normal, Sport, and Track—drivers can fine-tune the suspension to their liking, while Track mode even allows for more detailed manual adjustments.

On the braking side, the GT3 RS gets a serious upgrade too. Steel-sheathed brake lines offer a more direct pedal feel and faster response. Plus, for those equipped with the ceramic composite brakes, there’s an option to add racing brake pads that reduce fade and deliver consistent, high-performance stopping power, even under extreme conditions. This package is built for precision and control—whether you’re on the road or pushing the limits on the track.

For those who want to show off their Manthey Racing upgrade, there are some cool optional extras like illuminated carbon-fiber door sills with “Manthey” in red and white, LED door projector lights, and stylish decals for the wheel covers and doors. You can even add a towing eye for track days, fitted to the front or rear.

The Manthey Racing kit will be available outside Europe starting in March 2025, and it’ll cost around $79,973 (excluding installation at a Porsche dealer). It’s the ultimate performance upgrade with a bit of flair for those looking to make a statement.
