RAYS 57CR SPEC D

RAYS gramLIGHTS 57CR SPEC D - Competition-Tuned Cast Monoblock with Knurling Technology

The Drift-Sport Variant of the 57CR Line, Built for Aggressive Sizing and Maximum Traction

RAYS gramLIGHTS 57CR SPEC D is a cast aluminum monoblock wheel developed by RAYS for the drift and sport compact segment. Building on the proven 57CR architecture, the SPEC D introduces an aggressive spoke-to-center geometry that varies by rim width to balance stiffness and weight, combined with knurling inherited from the 57XR - the design that won D1 Grand Prix in 2022.

RAYS gramLIGHTS 57CR SPEC D Design and Engineering

The 57CR SPEC D carries a seven-spoke design where spoke depth and cross-section shift progressively with rim width, maintaining consistent stiffness-to-weight ratios from 7J through 10.5J. The knurling surface treatment on spoke surfaces reduces tire slip under high lateral loads - a technique developed in RAYS' active D1 Grand Prix program and transferred directly to the 57CR SPEC D. The wheel is produced in Matte Super Dark Gun Metallic (AZZ), a low-sheen dark metallic finish suited to motorsport aesthetics.

RAYS gramLIGHTS 57CR SPEC D Design Features

Knurling Technology: Surface knurling is applied to the spoke faces, creating a micro-texture that improves tire bead grip under drift and aggressive cornering loads - derived from the D1 Grand Prix-winning 57XR program. Variable Spoke Geometry: Spoke profile adapts by rim width, optimizing stiffness and weight distribution for wide-body and standard-body applications from 17" through 19". JWL+R Spec 1 Certification: Each wheel is tested and certified to JWL+R Spec 1, ensuring structural integrity for performance street and circuit use.
