Performance Street and Track Wheel Fitment
Wider fitments for enhanced performance
These are our most popular 987 fitments perfect for drivers that want an increase in wheel and tire width over stock without the compromise of having to heavily modify the car. Some modifications may be needed depending on the tires and wheels run. These fitments offer a dual-duty option for those who want to use these wheels on the street and drive to the track for an HPDE. Summer and Extreme Performance tires are what we recommend for these wheel fitments.

Hardcore Track Wheel Fitment
Track focused fitments that require significant modifications
These wheel and tire configurations are best suited for hardcore track junkies and club racers competing for a spot on the podium. Everything from Extreme Summer tires to full Racing Slicks are commonly used depending on your experience behind the wheel, class rules, etc. Most notably, these fitments incorporate wider 9” front wheels which provide superior tire sidewall support over the more "generic" 8.5" front wheels typically found on a 987. These fitments prioritize performance over ease of installation. Some of the below options may be a direct fit but other require increased camber through camber plates to ensure fender clearance.
