The 57DR has a six-spoke design based on the original gramLIGHTS model 57D. The special 'Admiral Blue' color that accentuates the 57DR's sportiness. The color is not the only thing that makes it special; it also introduces a performance feature cultivated in the drifting scene, Knurling Finish. Knurling Finish reduces slippage between wheel and tire, enabling full power transfer to the road.
