15x12in Aluma Star Wheel 5x4.75in 3-3/8in BS

The 15x12in Aluma Star Wheel 5x4.75in 3-3/8in BS from WELD RACING is engineered for serious automotive builders who demand lightweight performance without compromising structural integrity. This is the wheel choice for drag racing, street rods, muscle car restorations, and any high-performance application where rotational mass directly impacts acceleration and handling. The Aluma Star design has been the gold standard in racing circles for decades, trusted by competitors and enthusiasts who understand that every pound shed from the wheel translates to measurable gains in ET times and overall vehicle dynamics.

WELD RACING's 15x12in aluminum construction delivers a featherweight 16.78 lbs per wheel—a critical advantage over cast or forged steel alternatives that can weigh nearly twice as much. The 5x4.75 bolt pattern accommodates classic General Motors platforms, Chrysler B-body vehicles, and select Mopar applications, while the 3-3/8 inch backspace geometry positions the tire for optimal weight transfer and brake clearance. The distinctive Aluma Star spoke pattern provides superior rigidity while maintaining the minimal material footprint necessary for unsprung weight reduction; this geometry has been validated across thousands of high-horsepower builds, from bracket racing to street performance.

Ideal for vintage Chevrolet, Pontiac, Oldsmobile, and Buick platforms, as well as classic Dodge and Plymouth models, this wheel integrates seamlessly into restoration projects seeking period-correct aesthetics with modern performance gains. Installation requires a 5x4.75 hub and standard lug nuts; verify your vehicle's backspace requirements and brake drum or caliper clearance before ordering. Whether you're building a street-legal drag car, restomod muscle car, or weekend bracket racer, the 15x12in Aluma Star Wheel delivers the uncompromising lightweight advantage that separates competitive builds from the rest.
