Our most popular street wheel design yet The Turbomac wheel was co-designed by Ken Block and Fifteen52. Inspired by the 5-spoke Tarmac, with a vented outer ring to help cool your brakes, the Turbomac was designed with both form and function in mind. Very strong and relatively lightweight, this wheel has true motorsport built into it’s DNA. Truly unique, and very versatile look – give your build that modern yet iconic Rally sport look your build is begging for.
