RAYS Volk Racing ZE40 M-Spec

RAYS Volk Racing ZE40 M-Spec - Evolved Forged Monoblock with M-Spec Spoke Architecture

The Next Generation of Japan's Most Acclaimed Performance Wheel

RAYS Volk Racing ZE40 M-Spec is a forged aluminum monoblock wheel built on the proven ZE40 platform, developed with an M-Spec spoke geometry that recalibrates the structural relationship between spoke profile and barrel for improved torsional stiffness without increasing rotational mass. Manufactured in Osaka, Japan to JWL+R Spec 2 standard, the ZE40 M-Spec continues the unbroken line of Volk Racing engineering that has defined Japanese performance wheel design across multiple decades of motorsport and road use.

RAYS Volk Racing ZE40 M-Spec Design and Engineering

The M-Spec designation applies to a refined spoke cross-section that redistributes material in the transitional zones between spoke face and barrel wall. RAYS Advanced Machining Technology (A.M.T.) produces the characteristic deep-cut lettering across the barrel, functioning simultaneously as brand identification and a structural surface treatment. Anti-slip bead knurling derived from Formula 1 tire retention technology runs across the spoke inner faces, preventing tire rotation under sustained high lateral load. Black high-speed air valves are fitted as standard equipment, specified for continuous high-speed operation where conventional rubber valves would fail under centrifugal force.

RAYS Volk Racing ZE40 M-Spec Technical Specifications

Construction: forged aluminum alloy monoblock, 1-piece. Diameters: 15- to 19-inch. Widths: 6J to 12J. Safety certification: JWL+R Spec 2. Standard finishes: Matte Black and Bronze Almite. Additional color options available through the RAYS optional color program.

RAYS Volk Racing ZE40 M-Spec Finish Options

The ZE40 M-Spec is offered in Matte Black and Bronze Almite as catalog finishes. Bronze Almite applies an anodizing process that bonds color into the aluminum surface at a molecular level rather than depositing a paint layer - producing a finish that resists chipping and fading through track and road use alike. The RAYS optional color program extends availability to additional finishes on confirmed order.

RAYS Volk Racing ZE40 M-Spec Vehicle Fitment

The ZE40 M-Spec is designed for sports coupes, performance saloons, and lightweight track-day vehicles where reducing unsprung rotational mass produces measurable improvements in handling response and powertrain efficiency. The 15- to 19-inch diameter range covers the specifications required by Japanese sports cars including the GR86, BRZ, Civic Type R, NSX, and Mazda ND Roadster, as well as broader performance fitments across European and domestic markets. The 6J to 12J width range supports narrow street configurations and wide motorsport setups across rear-wheel-drive platforms.

Any Vehicle, Any Specification

The RAYS Volk Racing ZE40 M-Spec is available through Hodoor Wheels across the full 15- to 19-inch size range in all standard and optional finish programs. Custom bolt patterns, offset specifications, and RAYS color program orders can be arranged for specific vehicle fitments and build requirements.
