The TE37 Saga SL M-Spec is the overseas-exclusive, weight-obsessed evolution of the TE37 SL line, the successor to the legendary TE37SL Black Edition III. It keeps everything that defined the SL series: the TE37 racing concave face, diamond-cut machining at the center hole and rim flanges that strips weight without sacrificing strength, and the clear black finish that makes the machining pop.
Forged as a 1-piece wheel and validated to RAYS' JWL+R Spec2 standard, the SL M-Spec is built purely around strength, rigidity, and low weight. The bead seat uses a knurling finish to resist tire slippage under high traction, the kind of detail that matters when you're putting power down on a track. Made in Japan, with A.M.T. machined lettering.
This set is finished in Pressed Black (PB), a deep clear-black that reveals the diamond-cut detail in the light. It ships with RAYS' signature Luminous Yellow spoke stickers and air valves. The renewed hole shape allows a center cap to be fitted (sold separately).
This is the 18x9.5 +39 5x114.3 specification, a classic performance fitment for Subaru and the wider 5x114.3 sport-compact world. Sold as a set of four.
