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.

These aggressive wheel specs will require supportive modifications commonly found on track cars. 17” wheels keep weight and tire costs to a minimum, allow for taller tire sidewalls, and will still clear factory STI Brembo brakes as well as a variety of aftermarket BBKs.

Aftermarket coilovers with a slimmer silhouette in comparison to the stock struts are required. Not all aftermarket coilovers provide a slim enough silhouette to accommodate 9.5” wheels without the use of spacers, so please contact an APEX product expert if you have any questions.

Brake Clearance Information

In the engineering phase of wheel development we 3D scan factory brakes and review 2D aftermarket brake templates in order to optimize our barrel profiles and spoke curvatures. As a result, our wheels offer massive brake clearance so you can run the smallest possible wheel diameter. The following brakes have been tested and confirmed to clear our wheels.

Should I Dial in Negative Camber, and How Much is Right for me?

Whether you are a casual weekend track warrior that still enjoys your car on the street, or a hardcore racer competing for a spot on the podium, negative camber is a vital part of chassis setup that has many benefits. Not only will adding negative camber create more room for wider wheel and tire configurations, it more importantly improves handling, turn-in and tire longevity.
