Porsche 991 911 GT2 RS Manthey Kit: All The Details

The Manthey Performance Kit for the Porsche 911 GT2 RS is now available in North America for $113,140 before taxes and installation.

Aerodynamic improvements include additional flaps on the front spoiler, a carbon underbody, and air guide elements near the front wheels. These changes, along with a new rear spoiler, modified diffuser, and aerodiscs for the rear wheels, significantly increase downforce. At 124 mph, downforce rises from 108 to 154 lbs. on the front axle and from 205 to 440 lbs. on the rear axle.

The coilover suspension, refined through motorsport expertise, offers customizable settings—three at the front and four at the rear. The magnesium wheels, available in a range of finishes including Brilliant Silver and Aurum, reduce unsprung weight by approximately 25 lbs. An upgraded water tank for the intercooler spray system increases capacity by 2.3 gallons to extend refill intervals.
