TE037 Dura is one of the most famous wheels from Rays that still preserves its original design of TE37s. It is improved with more rigibility and its lightness competes with any other super wheels
Amongst that number of aluminum, the toughest of them all is the Ultra Super Duralumin, which was introduced for the TE037 DURA. Preserving the constant flow of metal grain through RAYS Original Design Mold Form Technology, the Ultra Super Duralumin shows its original unparalleled strength. The design is based on the 2017 SUPER GT500 with improved strength and lightness while remaining true to the conventional configuration of six-spoke RAYS. The spoke side's vertical wall is a reduction in thickness which is a procedure applied to skilled competition spokes when effectively machining and drilling pockets without compromising the rigidity.
