Weld Racing 71HP8050W21A RT-S S71 Polished Forged Aluminum Wheel 18x5 5x115 2.1in Backspace High Pad

The Weld Racing RT-S S71 is a premium 3-piece forged aluminum wheel that brings race-proven engineering to the street. Built using primary forging-grade aluminum alloys, this 18x5 polished wheel features a forged billet center paired with cold-forged rim shells — delivering an exceptional strength-to-weight ratio in a welded modular construction.

This specific fitment measures 18 inches in diameter by 5 inches wide with a 5x115mm bolt pattern, 2.1-inch backspace, and a -23mm offset (High Pad). The high pad mounting configuration is engineered to clear modern, multi-piston opposed calipers — including factory-installed Brembo systems and performance aftermarket brake systems from Baer, Brembo, and Wilwood.
