The new 57Xtreme is the latest model out of the Gram Lights line and is one of the most concave wheels that Rays has produced to date! This wheel features a prominent split 6 spoke design that is sure to enhance the look and performance of any vehicle! An SP Spec version is also offered and this particular spec implements Rays side cut technology allowing additional weight savings without sacrificing wheel strength. Rays Engineers were able to accomplish this with the side cuts along with a unique bridge design on each spoke, much like the Volk G12. The SP Spec also features an aluminum rigidity ring which allows for even more weight savings while maintaining the integral strength of the hub area (not available in 17 inch)
