RT-S S81 Series Wheel 18x11 5x4.75 BC 7.6 BS

The RT-S S81 Series Wheel 18x11 5x4.75 BC 7.6 BS by WELD RACING represents purpose-built engineering for serious automotive enthusiasts and professional builders who demand precision fitment and durability in extreme driving conditions. Designed for high-performance applications—drag racing, road course competition, and show vehicles—this 18-inch wheel delivers the aggressive stance and structural integrity required for modified vehicles pushing limits. The S81 Series sits at the intersection of function and form, engineered to complement custom suspension setups and brake systems while maintaining the reliability expected from WELD RACING's legacy in motorsports.

This wheel features an 18x11-inch diameter and width configuration, designed specifically for the 5x4.75-inch bolt pattern common to Chevrolet platforms including Camaro, Corvette, and truck applications. The 7.6-inch backspacing (BS) and 7.6-inch bore center (BC) geometry position the wheel for optimal suspension clearance without compromising brake cooling or creating unwanted rubbing under compression. At 31.1 pounds per wheel, the S81 delivers a competitive weight-to-strength ratio, critical for both acceleration response and unsprung mass reduction in performance builds. WELD RACING's manufacturing process ensures concentricity and structural consistency across the face and rim, reducing vibration at highway speeds and extending tire life on multi-purpose vehicles.

Mechanics and builders favor the RT-S S81 Series for Chevrolet Camaro, Corvette, and Chevy truck platforms where deep dish styling meets functional performance requirements. The generous 11-inch width accommodates modern wide-body kits and drag slick setups, while the precise backspacing ensures compatibility with coil-over and air suspension systems. Installation requires standard lug nut hardware matching your vehicle's specifications; verify your specific bolt pattern and clearances before ordering, particularly if running aggressive offsets or modified suspension geometry. This wheel suits street performance, autocross, drag racing, and show applications where reliability and proven WELD RACING quality are non-negotiable.
