6:43.300 Minutes. The Nürburgring Record That Changed Everything.

70% More Downforce. 186 MPH in the Wind Tunnel.

Zero Compromise.

The Manthey kit for sale transforms the GT2 RS into a ground-effects weapon. At 124 MPH, front downforce jumps from 108 lbs to 154 lbs. Rear downforce explodes from 205 lbs to 441 lbs. Overall: 70% more grip, tested in Weissach's eight-meter wind tunnel with carbon blades spinning at 186 MPH.

The secret? A carbon underbody with front wheel air deflectors and apron flaps. A massive rear wing attached directly to the reinforced body—not the boot lid—with special supports. A carbon rear diffuser and aerodiscs that cut turbulence while increasing efficiency.

The aero balance shifts. Driving stability soars. And every surface has been tortured in the same wind tunnel that shapes Porsche's race cars.

This is downforce you feel in your chest. Downforce that lets you brake later, carry more speed, and trust the car at limits that terrify everything else on track.

3-Way Adjustable. Direct-Mount Wing. Race-Car Precision.

The Porsche Manthey kit for sale includes suspension developed across countless international race tracks—especially the Nürburgring-Nordschleife.

Front axle: MacPherson strut in upside-down design with high-strength aluminum housing tube. 3-way adjustable damping with tool-free adjustment wheels on the external reservoir. Independent compression in low and high speed. Rebound adjustment at the damper base. Aluminum support bearings with easy camber adjustment.

Rear axle: Aluminum shock absorber with 4-way adjustment—compression and rebound, low and high speed—all tool-free.

Standard front axle lift? Fully retained. The setup that set the record is the setup you get.

2.4 Gallons More Coolant. Maximum Power, Longer.

The Porsche Manthey kit for sale adds an additional 2.4 gallons (9 liters) to the charge air cooling water tank. The result? Significantly extended range between refills and longer maintenance of optimal intake air temperatures.

Maximum power output sustained. Thermal management mastered. Another detail that separates a record-breaking machine from a fast car that overheats.

Manthey thinks of everything. So you can focus on one thing: driving.

25.1 lbs Lighter. Unsprung Mass Decimated.

The Manthey kit for sale requires the 20/21-inch GT2 RS magnesium wheel set—and for good reason. At 25.1 lbs lighter than aluminum alloy wheels (11.4 kg), rotational inertia plummets. Acceleration sharpens. Direction changes become telepathic. Suspension response transforms.

Available in brilliant silver, black silk gloss, aurum silk gloss, white gold metallic silk gloss, or platinum silk gloss.

Fitment: 9.5 J x 20 front with 265/35 ZR 20 tires, 12.5 J x 21 rear with 325/30 ZR 21 tires. Porsche recommends Michelin Pilot Sport Cup 2 R for maximum grip.

The wheels that helped set the record. Now available for your garage.
