The Weld Racing S71 RT-S is a legendary street and strip wheel that brings proven racing technology to performance street applications. Built using a 3-piece modular construction, the S71 features a forged billet aluminum center and cold-forged rim shells welded together for an exceptional strength-to-weight ratio. This specific wheel measures 18 inches in diameter by 8 inches wide, fits a 5x4.75 inch (5x120.65mm) bolt circle, and provides 4.700 inches of backspace — ideal for a wide range of classic and modern muscle car applications.

The S71 is finished with a black anodized center for a clean, aggressive drag-race-inspired appearance. The medium pad mounting configuration is engineered to clear high-performance factory brake systems common on performance vehicles from the late 1980s onward, as well as many aftermarket disc brake upgrades.
