Porsche Cayman GT4 Forged Wheels By Manthey Racing

Porsche Cayman GT4 Forged Wheels By Manthey Racing

Forged Innovation For Porsche Cayman GT4 Owners

Manthey Racing has a reputation for building performance components that meet the demands of serious enthusiasts and professional teams alike. Their Forged Lightweight Wheel Set for the 981 Porsche Cayman GT4 is the latest example, created in close collaboration with Porsche’s Development Centre in Weissach. These wheels go far beyond cosmetic appeal; they deliver measurable improvements in responsiveness, control, and durability while maintaining OEM precision and warranty compliance.

Reducing unsprung and rotating mass is one of the most effective ways to transform a car’s dynamics, and Manthey’s forged construction cuts as much as 11.8 kilograms per set compared to stock wheels. That drop in weight directly benefits spring and damper response, sharpens steering input, and makes the car feel more alive on track or on winding back roads. It is the type of refinement that doesn’t just show up on lap times, but in every corner and braking zone.

Track-Proven Development

Manthey Racing’s name carries weight for good reason. Based at the Nürburgring and rooted in motorsport excellence, the company has decades of success in endurance racing with Porsche factory support. That experience translates directly into the wheels offered for the Porsche Cayman GT4, with testing and development shaped by real-world racing environments. Customers benefit from components that aren’t simply designed for visual appeal, but for proven performance where it matters most, on the stopwatch.

The forged wheel set is offered in three distinct finishes: Brilliant Silver, Neodyme, and Satin Gloss Black, allowing owners to tailor the appearance of their Porsche Cayman GT4 to their personal taste while enjoying the same high level of engineering behind each option. Each set includes four wheels, designed for use with OEM Porsche hardware, though they ship without tires, valves, or TPMS sensors.

Porsche-Grade Fitment And Warranty Protection

One of the standout advantages of Manthey Racing wheels is their direct-fit design. Offered in factory-matched sizing, 20×8.5 +61 up front and 20×11 +50 at the rear, they install seamlessly without altering suspension geometry or requiring additional modifications. Porsche owners can take comfort in knowing that these wheels are built to the same quality standards as OEM equipment and preserve eligibility for the Porsche Approved Warranty.

Manufacturing also remains under Manthey’s complete control. Since July 2023, Manthey has operated its own lightweight wheel production facility, allowing the company to insource development, machining, finishing, and final inspection. This ensures consistency, rapid adaptation to customer needs, and uncompromising quality throughout the process. Every wheel undergoes comprehensive validation and quality control to ensure the kind of dependability expected from Porsche-level hardware.

Specifications And Applications

The Manthey Racing Forged Lightweight Wheel Set has been engineered exclusively for the 981 Porsche Cayman GT4, covering model years 2015–2016. The front wheels measure 20 inches in diameter with an 8.5-inch width, a +61 offset, and a 71.6mm center bore. At the rear, the wheels are 20 inches in diameter, 11 inches wide, with a +50 offset and the same 71.6mm center bore.

This configuration mirrors the OEM fitment to guarantee compatibility with factory hardware while maintaining the Porsche Cayman GT4’s precise handling balance. By keeping sizing consistent with Porsche specifications, Manthey ensures a direct installation that delivers immediate performance benefits without requiring additional modifications or compromising warranty eligibility.

A Legacy Of Porsche Excellence

 

Manthey Racing continues to bridge the gap between racetrack innovation and road-going precision. From aerodynamics and braking to suspension and wheels, every product they release is engineered with one purpose in mind: faster laps without sacrificing drivability. For Porsche Cayman GT4 owners, the Forged Lightweight Wheel Set represents an opportunity to experience the same engineering philosophy that has made Manthey a dominant force in Porsche endurance racing.
