Founded in Osaka in 1973, RAYS Co., Ltd. (also known as RAYS Engineering) is a premier Japanese wheel manufacturer whose legacy is rooted in motorsports—from Le Mans victories to Formula 1 and WEC triumphs with Toyota and Mazda. RAYS pioneered forging technology—stalling billet aluminum forging, proprietary RM forging, cold spinning, CNC machining, and precision inspection—to deliver ultra-light, high-strength wheels.

Their flagship Volk Racing line, including the iconic TE37 introduced in 1996, revolutionized forged wheel design with a 3.7 kg weight and race-grade durability. Complemented by cast models such as Gram Lights, Versus, Team Daytona, and Homura, RAYS blends performance, aesthetics, and precision engineering. 

Supplying wheels to factory race teams across Super GT, FIA championships, BTCC, Formula 1, endurance, rally, and more, RAYS channels track-proven data into every wheel they produce. From road-going sport compacts to off‑road rigs, RAYS continues to set the benchmark for performance, quality, and Japanese craftsmanship.
