As seen in Ken Block's Gymkhana SIX video* his new Turbomac wheel was actually co-designed by Fifteen 52 and KB himself.
Essentially a Tarmac (KB's previous signature wheel design) center with a vented 'turbo' ring, why we call it the TurboMac should need no explanation. Very strong and relatively lightweight, this is very much a motorsports-quality wheel.
17x8 and 18x9 available first, with other sizes coming later in 2015.
Available in silver or white with the world-famous '52' 3D center cap.
*Turbo-fan wheel covers (as seen in the video) are not included
