Porsche 981 Cayman GT4 Clubsport Wheels

981 GT4 Clubsport Wheel Performance

Being a factory race car, the 981 GT4 Clubsport wheel setup is quite dialed in. With racers generally having multiple sets of wheels already we did not want to cause chassis balance changes by adjusting the offset. For this reason we stuck with the ET41 front and ET47 rear to allow you to move between sets with minimal effects. This will be available in our Enduro line of Forged wheels, the VS-5RE. Feel free to check out our Porsche 981 Cayman GT4 Clubsport Fitment Guide for more information.

A Brief History of the 981 Cayman GT4 Clubsport

The first factory Cayman race car from Porsche motorsport. We do offer 981 GT4 clubsport specific wheels, but what differentiates the Clubsport from the street GT4 and what is similar between the two. The biggest similarity is the engine. The Naturally aspirated 3.8L from the street car remains with the same power of 385 hp. Transmission is a departure from the street car, gone is the 6-speed manual and in is a 6-speed PDK transmission. The body structure remains the same with a Porsche motorsport roll cage installed among other safety items like fire suppression and main power kill switches. There are numerous chassis changes from the street car, to start the inclusion of lightweight front suspension components of the 991 GT3 cup car. A modified version of the GT3 Cup car's strut is used on the rear of the strut based clubsports rear suspension. PFC brakes are another large upgrade for the racing focused clubsport. This included 380mm rotors front and rear with 6 piston front calipers and 4 piston rears. A 12 setting ABS system is implemented as well to cover the scope of conditions that one can expect in racing. The electronic stability control system was also tuned for the use of racing slicks. The compact nature of the PFC caliper is what allows for the use of 18” wheels on the clubsport where the street car can only use down to a 19” wheel. The 981 Cayman GT4 Clubsport wheels we offer are almost identical to the factory wheels. At 18x9”ET41 and 18x10.5”ET47 this will be a direct replacement for the factory setup without any changes to the location of the tires centerline. The same 25/64-18 and 27/68-18 tires will continue to be used along with the use of MR lug nuts.
