Every hardcore racer dreams about reducing unsprung mass on their vehicle. In a vehicle with a suspension, the unsprung weight (or, more properly, the unsprung mass) is the mass of the suspension, wheels and other components directly connected to them, rather than supported by the suspension.
At the SEMA show in Las Vegas, HRE in collaboration with Dymag has displayed their new Carbon Fiber wheels. The wheels are made of Carbon Fiber with a magnesium hub. The carbon portion is supplied by Dymag, while the magnesium centerpiece is supplied by HRE.
