Manthey's Newest Performance Kit

Porsche is now offering a Manthey Kit for the current 911 GT3 RS (992) for even higher performance on track.

Product Highlights:

• More than a Ton of Downforce at 177 mph -- The spoiler lip, now featuring an enlarged wing profile, is reinforced with carbon fiber elements for added stability. In combination with the newly designed Gurney flaps on the wheel arches and dual dive planes positioned on either side of the front bumper, this improved spoiler lip enhances downforce on the front axle. At 177 mph, the 911 GT3 RS with Manthey Kit produces more than a ton of downforce. This enables higher speeds on fast and medium-speed corners and maximizes vehicle stability.
• Semi-active Coilover Suspension -- The spring rates of the semi-active coilover suspension have been adjusted for the higher downforce figures. The spring rates were increased by 30 percent on the front axle and by 15 percent on the rear. Four wheel- and three body-acceleration sensors – along with a newly developed control unit – ensure fully automatic damper tuning that is extremely fast and even more precise than before.
• Racing Brake Pads Specially Optimized for Track Days -- The Manthey Kit's braking components are tailored to the requirements of driving on the racetrack. The steel-sheathed brake lines provide an even more direct pedal feel and a faster response time. Optional racing brake pads are available for cars with the Porsche Ceramic Composite Brake (PCCB). These pads have been specially developed for track-day use and reduce fading while also increasing responsiveness and control precision.

The Manthey Kit for the 911 GT3 RS can be ordered now and will be available in North America in March 2025. The manufacturer’s warranty for the 911 GT3 RS remains unaffected.
