Weld Racing 71MB8120B57A RT-S S71 18x12 Black Wheel 5x4.75 5.7in BS Medium Pad

The Weld Racing RT-S S71 is a three-piece forged aluminum wheel that brings WELD's proven racing technology to the street and strip. This specific configuration measures 18 inches in diameter by 12 inches wide, features a 5x4.75-inch (5x120.65mm) bolt pattern, and a 5.7-inch backspace (-20mm offset) with a medium mounting pad height — engineered to clear high-performance factory brake systems found on performance vehicles from the mid-1980s onward, as well as a wide range of aftermarket brake systems.

The wheel is built using a forged billet center paired with cold forged rim shells, then assembled via a unique welded process that delivers an exceptional strength-to-weight ratio. The center features a durable black anodized finish for lasting good looks under demanding use.
