Isringhausen Motorsports is pleased to offer this exceptionally well-preserved 2020 Porsche 718 Cayman GT4 Clubsport Competition showing just 477 miles from new. Originally sold new by Isringhausen Motorsports, this is a true one-owner example that has seen extremely limited use since delivery.
With only 477 original miles, this GT4 Clubsport represents an increasingly rare opportunity to acquire an extremely low mileage example. The car was very lightly used at Putnam Motorsports Park in Indiana and remains in outstanding original condition throughout, free from any on-track incidents or damage history.
This GT4 Clubsport Competition is further enhanced with a suspension system installed by Kelly-Moss Racing, including multi-link rear suspension kit, specially calibrated shocks engineered to improve overall balance, drivability, and track performance. The upgraded patented multi-link rear suspension system engineered by Jay O’Connell replaces the factory strut arrangement with a race-inspired multi-link design that significantly improves handling dynamics, high-speed stability, braking stability, and cornering performance. According to O’Connell, the system was developed using the 997 RSR’s rear suspension geometry as its benchmark and demonstrated gains of approximately 2.5 seconds per lap during back-to-back testing at Sebring on slick tires. The patented design has since been installed on more than 25 cars and delivers a more predictable, confidence-inspiring rear end at the limit.
The suspension has been further refined with custom-valved dampers that differ from the standard Manthey specification, featuring softer front valving and modified rear dampers specifically tailored to complement the car’s upgraded multi-link rear suspension. By replacing the factory rear strut assembly with a true coilover shock configuration, the system significantly reduces suspension friction while improving bump steer characteristics and camber control. The result is a more compliant, confidence-inspiring chassis with enhanced stability, improved rear grip, and a remarkably composed feel both at the limit and during corner transitions.
The car is also equipped with an M&M Race System insulated exhaust and manifold system from Germany ($8,320.00) enhancing performance, reducing heat soak, and delivering an aggressive motorsport-inspired exhaust note. In addition to the upgraded exhaust system, this GT4 has a COBB custom tune, sharpening throttle response and optimizing engine performance to deliver a more responsive and engaging driving experience.
The driver harnesses, window nets, and fire extinguishing system have all been recently replaced and are current, ensuring the car is properly equipped for immediate track use.
For those interested in PCA Club Racing, while this car will not be in class GTD2, it will fit right in to the GT3 class, which generally races along with all other GT4 race cars.
Included with the sale are the original wand, air jack stands, data cable, fuel pump-out system, books/manuals, and additional springs and shocks.
Extremely low-mileage GT4 Clubsport Competitions rarely become available, especially in this condition.
