The CarbonX construction utilizes a one-piece Dymag Performance Wheels barrel for the ultimate weight reduction and strength. Carbon construction reduces unsprung mass dramatically allowing for vast improvements in handling and ride quality. This reduced mass also allows a reduction in the moment of inertia which improves acceleration and braking performance. The overall result is a better performing car that looks incredible on the street and reduces lap times at the track. 1221 designed brand new concave profiles for the Absolut wheel line to produce a more concave profile than currently available. The end result is the lightest and most concave wheels available on the market today.
