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 to the factory suspension or alignment. Just bolt-on and enjoy!

While these wheel fitments can be used for track days and AutoX, performance will be left on the table. Drivers that prioritize performance should review our Performance Street & Track and/or Hardcore Track & Race sections below.

Performance Street and Track Wheel Fitment

Wider fitments for enhanced performance

  • Purple Porsche Cayman - VS-5RS in Brushed Clear
  • Blue Porsche Cayman - VS-5RS in Satin Bronze

  • 1 / 2

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. Most notably, these fitments incorporate wider 9” front wheels which provide superior tire sidewall support over the more "generic" 8.5" front wheels. A wider front wheel and tire combination will increase front end grip and close the stagger from front to rear resulting in sharper turn-in and less understeer. This is one of the easiest and most effective improvements you can make to your Porsche from a handling perspective.

We've optimized the offset of our 9" front wheels to to work well with the stock fenders, however, a wide variety of tire compounds can be used and some may require negative camber 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.
