Porsche 986 Boxster Wheel & Tire Fitment Guide

Vehicle Covered in this Guide 1997-2004 Porsche 986 Boxster & Boxster S chassis

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.

These bolt-on wheel fitments are ideal for enthusiasts enjoying their car day-to-day on the street, and they are typically paired with All-Season or performance oriented Summer tires. These wheel and tire configurations will improve the appearance and performance of the car without requiring modifications or adjustments to the factory alignment. Just bolt-on and enjoy!

Whether you enjoy spirited street driving or you are a weekend track warrior chasing lap times, these wheel & tire configurations are ideal for enthusiasts looking for a more dramatic improvement in performance and they are typically paired with performance oriented summer tires or track oriented r-compounds. Some configurations may require negative camber and fender rolling to fit properly. See fitment notes under each tire configuration below to see if modifications are required.

If you plan to track your car, we highly recommended dialing in negative camber regardless of whether your wheel/tire fitment requires it for fender clearance. Negative camber is vital for extracting the most performance and longevity out of your tires, and without the proper amount the outer shoulders of your tires will wear out prematurely and running tire costs will dramatically increase.
