The Weld Racing RT-S S71 is a purpose-built forged aluminum wheel that bridges the gap between hardcore drag racing performance and street-legal versatility. This specific configuration measures 18 inches in diameter by 10 inches wide, features a 5x4.75-inch bolt pattern, and an 8.2-inch backspace (69mm offset) with a Medium pad height — engineered to accommodate high-performance factory brake systems commonly found on performance vehicles from the late 1980s onward, including many popular aftermarket brake upgrades.

Constructed using Weld Racing's proven three-piece modular process, the wheel combines a forged billet aluminum center with cold forged rim shells, then permanently joined via a unique welded assembly. The center features a distinctive black anodized finish and the classic Weld Racing 5-spoke star design. This method delivers an exceptional strength-to-weight ratio without sacrificing durability under race or street conditions.
