After Mercedes tuner Renntech had its wicked way with the CLS63 AMG, giving the high-performance luxury four-door coupe some new aerodynamic parts courtesy of a custom body kit, wheel specialist ADV.1 Wheels added a set of its very own Track Spec ADV10.0 alloys. The bodykit remains a prototype but is expected to make it to production with few, if any, changes. The wheels measure in at 20 inches and have been finished with brushed gunmetal centers and a single tint brushed gunmetal outer that's one shade lighter.
