C&R Performance now offers Porsche Cayman radiators built by PWR in Australia and used by top teams in The IMSA Continental Tire ST series. The RHS radiator features 42mm dimple tube core and race fin technology for strength and unmatched heat rejection. The same radiators used by the winning 2016 Daytona 200 team are a must have for any performance upgrade on your 2006-2012 Cayman S. The same radiator will work in your daily driver as it mounts just like the factory cooler using OEM mounting provisions but provides optimum cooling that is demanded by Porsche Cayman S cars racing on the IMSA circuit or driven on the street.
