Whether you enjoy spirited street driving or you're a weekend track warrior chasing lap times, these wheel & tire configurations are ideal for CT5-V Blackwing owners looking for a more dramatic improvement in performance. They are typically paired with performance oriented summer tires or track oriented R-compounds and this category includes both staggered and square configurations to best suit each individual drivers priorities, goals and preferences for their vehicle.

We've optimized the offset of our wheels 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 Blackwing, we highly recommend 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.
