RAYS Volk Racing TE37SONIC SL CP·TK version is a limited-edition forged monoblock wheel produced exclusively for the Cockpit (CP) and Tire-kan (TK) retail chains in Japan. Built on the TE37SONIC SL platform - VOLK RACING's competition-heritage six-spoke monoblock for compact and kei class vehicles - the CP·TK version offers the SL architecture in a dedicated Black (BJ) colorway with a matching red spoke sticker set that defines the SL line's visual identity.
RAYS Volk Racing TE37SONIC SL CP·TK version - Design and Engineering
The TE37SONIC SL is engineered as a lightweight forged monoblock for 15- and 16-inch applications on Japanese domestic market compact vehicles. The SL spoke geometry maintains the TE37SONIC's race-derived six-spoke layout while tuning proportions for street and circuit use on kei-class and compact platforms. The CP·TK version delivers this platform in Black (BJ) - a deep, solid black that provides a strong visual contrast with the included red spoke sticker set - available exclusively through Cockpit and Tire-kan dealerships.
