Weld Racing 71MB7070B53A RT-S S71 17x7 Black Wheel Medium Pad 5x4.75 5.3in Backspace

The Weld Racing RT-S S71 is a premium 3-piece forged aluminum wheel engineered to bring race-proven technology to the street. Built in Kansas City, MO, USA, this 17x7.0" wheel features a black anodized center, a 5x4.75" bolt pattern, and 5.3" (33mm offset) backspacing with a medium pad hub design — ideal for high-performance factory brake systems first seen on 1965 Corvettes and on performance cars from the late 1980s onward, as well as many popular aftermarket brake setups.

The S71 is constructed using a unique welded 3-piece assembly process that joins forged billet center sections with cold-forged rim shells, delivering an exceptional strength-to-weight ratio without sacrificing durability. Three available mounting pad heights — low, medium, and high — allow this wheel to clear a wide range of brake packages, from drum brakes and early disc systems to modern multi-piston opposed calipers from Brembo, Wilwood, Baer, and others.
