The Weld Racing RT-S S71 (71MB8050N32A) is an 18x5.0 forged aluminum wheel finished in a black anodized center, engineered for performance street and strip use. This specific configuration features a 5x120mm bolt pattern, 3.2" backspace, and a 5mm offset, paired with a medium mounting pad height designed to clear high-performance factory brake systems found on performance cars from the late 1980s onward, as well as many popular aftermarket brake packages.
Weld Racing brings its racing technology to the street with a 3-piece modular construction using a unique welded assembly process. Each wheel is built with a forged billet aluminum center and cold-forged rim shells, delivering an exceptional strength-to-weight ratio that sets the RT-S line apart from cast alternatives. Wheels are manufactured using primary forging-grade aluminum alloys and are validated through F.E.A. (Finite Element Analysis) and in-house destructive testing for maximum safety and durability. The RT-S S71 is proudly made in Kansas City, MO, USA.
The S71 features the classic 5-spoke star design that has defined the Weld Racing aesthetic for decades, offering a bold motorsport look that transitions seamlessly from the drag strip to the street. Three brake pad clearance heights — low, medium, and high — are available across the S71 lineup to accommodate a wide range of drum, disc, and multi-piston caliper configurations.
