Some cars are fast. Some cars are rare. A select few become instant motorsport icons.
Isringhausen Motorsports is proud to announce the arrival of the world's first delivered Porsche 718 Cayman GT4 RS Clubsport MR 30, an extraordinary machine celebrating 30 years of motorsport excellence from Manthey Racing.
As the spiritual successor to the legendary 911 GT2 RS Clubsport 25, the MR 30 represents the ultimate and final evolution of Porsche's internal-combustion, mid-engine 718 platform. Limited to just 15 examples worldwide, this exclusive Clubsport features a commemorative dashboard badge identifying it as "ONE of 15 Produced," and we're honored that the very first customer-delivered example has arrived right here in Springfield.
Built for uncompromising performance, the MR 30 benefits from an extensive carbon-fiber lightweight package that includes redesigned body panels, aggressive aerodynamic enhancements, and a massive rear wing engineered to maximize downforce. Manthey also incorporated a high-efficiency cooling system and race-proven brake ducting derived from the GT2 RS Clubsport Evo to deliver exceptional durability during extended track sessions.
At its heart is Porsche's magnificent 4.0-liter naturally aspirated flat-six, producing 500 horsepower and revving to an unforgettable 9,000 RPM. Combined with lightweight Manthey wheels, specially tuned racing suspension, and a razor-sharp chassis, the MR 30 offers an experience few drivers will ever have the opportunity to enjoy.
Finished in Manthey's striking 30 Years Anniversary livery, complete with exclusive interior details and embroidered headrests, this car is more than a track weapon. It is a celebration of three decades of racing success and a landmark piece of Porsche motorsport history.
Interested collectors and racers are invited to contact the Isringhausen Motorsports team for private inquiries regarding this remarkable machine.
