Weld Racing 70HP0070W43A RT-S S70 Polished Forged Aluminum Wheel 20x7 4.3in. BS High Pad

The Weld Racing RT-S S70 is a premium 3-piece forged aluminum wheel engineered to bring proven racing technology to the street. Built at Weld's 140,000 sq. ft. manufacturing facility in Kansas City, MO, this wheel features a polished finish, a 20-inch diameter, 7.0-inch width, and 4.3-inch backspacing — ideal for high-performance muscle cars and street machines demanding both strength and style.

Weld's 3-piece welded forged construction uses aircraft-quality forging-grade aluminum alloys for the rim shells and center, assembled via a unique welded process. The result is a wheel that delivers a superior strength-to-weight ratio compared to cast alternatives, without sacrificing structural integrity under hard launches or high-stress driving conditions.

Key Features:

• 3-piece welded forged construction using forged rim shells and forged billet center for optimal strength and weight savings
• High pad (HP) design provides increased brake clearance — 2.05 in. from the peak of spoke curvature — compatible with large multi-piston calipers and oversized rotors
• Polished finish for a classic, high-gloss appearance
• 20x7 sizing with 4.3-inch backspacing for precise fitment
• Manufactured from primary forging-grade aluminum alloys for maximum durability
• Tested via Finite Element Analysis (F.E.A.) and in-house destructive testing to verify safety and performance
• Non-beadlock design for street and strip use
• Sold individually

Lug Nut Note: 17", 18", and 20" diameter Weld RT-S wheels require conical seat lug nuts. Short mag shank lug nuts are required for some 15" diameter applications. Factory OEM lug nuts are not compatible — always use the correct Weld-specified hardware to ensure safe installation.

Weld Racing has been the wheel of choice for championship-level drag teams and performance enthusiasts since 1967. The RT-S S70 carries that same motorsport-proven engineering straight to your street build.
