In the video below the “Underground Rim King” goes through the installation process of adding 28-inch DUB Swyrl Spinners to a Roush 427R Convertible Mustang.

The DUB Swyrl Spinners run a cool $1,000 a wheel plus whatever the tires cost. There goes your handling and performance capabilities of the Roush 427R Mustang. Check out the video below.
