RAYS Volk Racing ZE40

RAYS Volk Racing ZE40 - The Iconic Japanese Forged Monoblock for Track and Street

Forged Monoblock Precision from Japan's Most Decorated Performance Wheel Brand

RAYS Volk Racing ZE40 is a forged aluminum monoblock wheel built in Osaka, Japan - a model that has defined the standard for lightweight performance wheels across multiple motorsport disciplines and generations of road-going sports cars. Engineered for drivers who demand the highest ratio of structural rigidity to mass, the ZE40 delivers a refined 10-spoke architecture developed through decades of racing application.

RAYS Volk Racing ZE40 Design and Engineering

The ZE40 face presents four distinct concave spoke profiles across its size range, each geometrically calibrated to maintain ideal spoke tension and visual proportion at every diameter and width. RAYS Advanced Machining Technology (A.M.T.) produces the deeply cut lettering across the barrel face - a signature feature that identifies genuine Volk Racing hardware and simultaneously functions as a structural treatment to increase surface rigidity without adding weight.

Anti-slip bead knurling derived from Formula 1 racing technology runs along the spoke inner faces, preventing tyre rotation under extreme cornering loads and sustained high-lateral-g conditions. Black high-speed air valves are fitted as standard, rated for continuous high-speed use where conventional rubber valves would fail under centrifugal force. Every ZE40 carries JWL+R Spec 2 certification - the Japanese safety standard for race-use wheels that exceeds the standard JWL specification by a substantial margin.

RAYS Volk Racing ZE40 Technical Specifications

Construction: forged aluminum alloy monoblock, 1-piece. Diameters: 15- to 18-inch. Widths: 5.5J to 11J. Safety certification: JWL+R Spec 2. Standard finishes: Diamond Dark Gunmetal (MM) and Bronze Almite (BR). Optional finishes: 18 color variants available through the RAYS color program, including Dash White, Matte Black, Diamond Black, MAG Blue, Diamond Silver, Dark Gunmetal, Hyper Blue, Racing Green, Metallic Red, Shining Light Metal, Shining Black Metal, and Shining Bronze Metal.

RAYS Volk Racing ZE40 Finish Options

The ZE40 is offered in two catalog finishes - Diamond Dark Gunmetal and Bronze Almite - and in 18 optional colors through the RAYS custom color program. Bronze Almite uses an anodizing process that molecularly bonds color to the aluminum surface rather than depositing a paint layer, producing a finish that resists chipping and fading through extended track and street use. Diamond Dark Gunmetal applies a metallic flake coating for depth and color shift under varying ambient light conditions.

RAYS Volk Racing ZE40 Vehicle Fitment

The ZE40 is designed for sports coupes, lightweight performance saloons, and track-day vehicles where reducing unsprung and rotational mass produces measurable improvements in handling response and acceleration. The 15- to 18-inch diameter range covers the specifications most commonly required for Japanese sports cars including the GR86, BRZ, Civic Type R, Integra, and MX-5, as well as European hot hatch fitments. The 5.5J to 11J width range supports narrow street fitments and wide aggressive configurations for rear-wheel drive and motorsport applications.

Any Vehicle, Any Specification

The RAYS Volk Racing ZE40 is available through Hodoor Wheels in the full size range from 15- to 18-inch across all standard and custom finish options. Custom bolt patterns, offset specifications, and RAYS optional color programs can be ordered for specific vehicle fitments and build requirements.
