Gram Lights: RAYS Engineering's Performance Wheel Line for Enthusiasts

Gram Lights is a performance wheel brand produced by RAYS Engineering, the Osaka, Japan-based manufacturer that has been at the forefront of wheel innovation since 1973. While RAYS is perhaps best known globally for the premium Volk Racing forged lineup, Gram Lights was introduced in 2001 to occupy a distinct and important role: delivering genuine RAYS quality and engineering at a more attainable price point. The result is a lineup of cast and flow-formed wheels that have become a fixture in time attack, drift, autocross, and grassroots motorsport communities worldwide.

The RAYS Pedigree Behind Every Wheel

What separates Gram Lights from other cast wheel brands is the factory and standards behind them. Every Gram Lights wheel is manufactured in Japan under RAYS Engineering's strict quality control processes, and the brand's wheels meet JWL+R Spec. 2 inspection standards — the same rigorous benchmarks applied across the broader RAYS lineup. RAYS has also supplied wheels to major racing organizations including Super GT and Formula D, and that motorsport knowledge filters directly into Gram Lights' design and manufacturing philosophy.

Many Gram Lights models are built using RAYS' proprietary RCF (RAYS Cast Flow Forming) method, which stretches and strengthens the wheel barrel after casting, improving structural integrity while reducing weight — delivering performance characteristics closer to forged construction than typical cast alternatives. RAYS has also patented its Advanced Machining Technology (AMT) and Hybrid Machining processes, which allow for intricate three-dimensional surface cuts and multi-layer finishes that give Gram Lights wheels a premium, forged-like appearance unique in the cast wheel segment.

The Iconic 57 Series

The defining product line for Gram Lights is the 57 series. The number "57" is a tribute to RAYS's motorsport heritage — when RAYS first entered competition in the 1970s, their racing cars carried that number, and it has been used on RAYS-supported vehicles ever since. Within this series, models like the 57DR (a six-spoke design beloved on track-prepped Civics, Miatas, and WRXes), the 57CR, and the competition-oriented 57C6 have become some of the most recognized wheel designs in global enthusiast culture. The lineup also spans specialized models for gravel rally, aggressive fitment builds, and modern domestic and import applications, giving drivers a wide range of options within a coherent design family.

Beyond the Wheel: Genuine Gram Lights Accessories

Gram Lights also produces a range of branded accessories to complement their wheels, including officially licensed Gram Lights wheel caps. These RAYS-branded center caps are engineered specifically to fit the 57 series and other Gram Lights models, providing a clean, finished hub appearance that completes the look of a proper build. Available in multiple finishes and color combinations, they are an easy way to refresh or customize a set of wheels while maintaining authentic RAYS styling.

Who Drives on Gram Lights?

Gram Lights has built a loyal following among drivers who want a performance wheel with real racing DNA — from weekend autocross competitors and time attack enthusiasts to street-tuned daily drivers who want an aggressive, lightweight fitment without the premium cost of a forged wheel. The brand is equally at home on a slammed street car as it is on a track-day weapon, and that versatility, backed by RAYS Engineering's decades of motorsport expertise, is why Gram Lights continues to be one of the most trusted names in the JDM performance wheel market.
