The Cayman GT4 lives for the moment the road turns to track. Precise. Balanced. Mid-engine perfection. The Porsche Manthey kit for sale at Porsche Lehi pushes that duality further—optimizing every system for the fight against the clock, without sacrificing the everyday usability that makes Porsche GT cars legendary.
Porsche engineers and Manthey’s Nürburgring specialists collaborated on road-approved components that deliver personal best times. The challenge? Never lose that connection between daily driver and weekend warrior.
Your GT4 is already exceptional. Manthey makes it unforgettable.
Porsche Lehi is a Manthey-Certified Performance Center, which means we don’t just sell this kit. We engineer your transformation.
This is decades of GT sports experience, complex aerodynamic simulation, and thousands of test kilometers at Weissach and the ‘Ring—distilled into a package that transforms your track days.
Better handling. Faster cornering speeds. Adrenaline you haven’t felt yet.Estre proved what’s possible. Now it’s your turn.
The Manthey kit for sale enhances the GT4’s already sophisticated aerodynamics with track-specific precision. Additional front underbody air-conduction elements optimize airflow beneath the nose, increasing front downforce where it matters most.
The carbon gurney flap on the standard rear wing creates the critical balance—higher rear contact pressure that keeps the mid-engine chassis planted through high-speed corners. New wing holders enable non-road-approved positions for track days when maximum output demands maximum aggression.
This isn’t added drag for visual effect. This is airflow managed by engineers who’ve won at the Nürburgring. Every element works in harmony. Every surface serves speed.
Track use punishes intake systems. Tire rubber. Brake dust. Road grime. The Porsche Manthey kit for sale includes specific mesh inserts for the lateral air inlets above the side skirts—stopping contamination before it enters the duct.
The result? Consistent intake temperatures. Reduced maintenance. More time attacking corners, less time cleaning filters. It’s a small detail that separates track-day pretenders from cars built to lap all day.
Manthey thinks of everything. Because the Nürburgring demands it.
The Manthey kit for sale transforms presence without transforming purpose. Illuminated carbon door entry panels glow with red and white Manthey lettering. Optional door graphics in white or black add individuality.
Optional towing loops in red, black, or yellow for track use—front and rear mounted, removable for street legality. Everything about this kit enhances everyday driving while announcing track-day intentions to those who recognize the signs.
Overall impression? A GT4 that looks as capable as it is. As exclusive as it performs.
With or without front axle lift, we’ve got your setup covered.
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.
Modulation improves. Reaction time drops. And suddenly, you’re braking later than your competitors—every single lap.
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.
