RAYS Volk Racing TE37 SAGA S-plus A.S.T. - Advanced Surface Technology on a Forged Monoblock Icon
Patent-Pending A.S.T. Finish Meets the TE37 SAGA S-plus Architecture
RAYS Volk Racing TE37 SAGA S-plus A.S.T. is a forged aluminum monoblock wheel that applies the A.S.T. (Advanced Surface Technology) finish to the established TE37 SAGA S-plus platform. Manufactured in Japan to JWL+R Spec 2 standards, the A.S.T. edition uses a patent-pending process that combines a polished three-dimensional surface texture with precision machining to create a finish that interacts dynamically with light. Available in A.S.T. Brushed (AB) and A.S.T. Crystal Buff (CB), the wheel delivers both the S-plus structural refinements and a visually distinct surface treatment that separates it from the standard SAGA S-plus range.
RAYS Volk Racing TE37 SAGA S-plus A.S.T. - Design and Engineering
The A.S.T. edition retains the full S-plus engineering foundation: revised spoke cross-sections that redistribute material in transition zones for maximum torsional stiffness, the six-spoke triangular face layout that defines TE37 visual identity, and the variable racing concave profile that adapts depth across the 18- to 20-inch size range. The A.S.T. surface process is applied over this structure to produce a finish that combines polished highlights with a dimensional texture invisible on conventional machined or painted wheels. The knurling finish on the bead seat area provides additional tire retention under high-grip conditions.
RAYS Volk Racing TE37 SAGA S-plus A.S.T. Design Features
A.S.T. (Advanced Surface Technology): a patent-pending surface treatment that combines precision polishing with three-dimensional texturing, producing a finish that shifts character across different lighting and viewing angles - distinct from conventional metallic paint or standard machining. S-plus Backside Geometry: the spoke backside profile is optimized at the barrel junction to improve load distribution while preserving the TE37 face silhouette that defines the model. Variable Racing Concave: the concave depth scales across the available size range to maintain correct visual proportions and structural performance at each diameter and width configuration. A.M.T. Lettering: RAYS Advanced Machining Technology engraves spoke identification marks directly into the three-dimensional spoke surface.
RAYS Volk Racing TE37 SAGA S-plus A.S.T. Technical Specifications
Construction: Forged aluminum alloy monoblock, 1-piece. Material: Forged aluminum alloy. Available diameters: 18 to 20 inches. Width range: 7.5J to 12J. Safety standard: JWL+R Spec 2. Finish options: A.S.T. Brushed (AB) and A.S.T. Crystal Buff (CB). Made in Japan.
RAYS Volk Racing TE37 SAGA S-plus A.S.T. Available Finishes
Available in two A.S.T. finishes: A.S.T. Brushed (AB) features a directional brushed texture with A.S.T. polishing that creates refined depth across the spoke face. A.S.T. Crystal Buff (CB) applies the polished A.S.T. process to deliver a warm, buffed surface character that reads differently from a standard clear coat. Both finishes showcase the patent-pending A.S.T. process exclusively available on this model variant.
