Gram Lights WGN2T42MSB Semi Gloss Black Wheel - 57NR 18x7.5 42mm

The Gram Lights 57NR is engineered by RAYS to be the flagship performance wheel of the R series — a cast aluminum alloy wheel that combines aggressive motorsport aesthetics with cutting-edge structural technology. This listing is for a single wheel in an 18x7.5 diameter and width, +42mm offset, and a striking Semi Gloss Black finish.

C-FORM Spoke Architecture: The 57NR features RAYS' classic 10-spoke design enhanced with a proprietary "C-FORM" cross-section between each spoke. This geometry dramatically increases rigidity and ensures the spokes maintain their geometry under high lateral and radial loads — technology drawn directly from the racing paddock.

H.S.PLUS Inner Rim Technology: RAYS developed "H.S.PLUS" (High Strength Plus) to reinforce the inner rim without adding weight. A specialized process controls the balance between tension and compression stress in the rim barrel, resulting in a wheel that handles hard cornering forces and high-horsepower applications with confidence.

A.M.T. (Advanced Machining Technology): RAYS' patented three-dimensional machining process allows brand logos and design details to be precision-engraved directly into curved surfaces — replacing the need for stickers or cast mold badges and delivering a premium, motorsport-grade finish.
