15 X 3.5in. Pro Star 5 X 4.5in. 1.375in. BS

The 15 X 3.5in. Pro Star 5 X 4.5in. 1.375in. BS wheel from Weld Racing is engineered for serious performance builders and street machine enthusiasts who demand lightweight, high-strength wheels capable of handling aggressive suspension geometry and heavy braking loads. This pro-level wheel is built for vehicles requiring premium fitment control and structural integrity in competitive or high-modification applications where standard wheels fall short.

Weld Racing's Pro Star series represents decades of racing heritage applied to street and track-focused builds that prioritize both aesthetics and measurable performance gains. At 15 inches in diameter with a 3.5-inch width, this wheel provides a compact, centered footprint ideal for vehicles with tight suspension clearances or classic proportions. The 5 X 4.5-inch bolt pattern accommodates specific vehicle platforms, while the 1.375-inch backspace (BS) measurement ensures precise caliper clearance and optimal brake cooling—critical factors when upgrading to larger rotors or performance brake packages.

Weighing just 14.2 pounds, the lightweight construction reduces unsprung mass, improving acceleration, braking response, and handling dynamics. Weld's manufacturing process delivers superior strength-to-weight ratios compared to heavier cast alternatives, making this wheel suitable for both street and strip applications without sacrificing durability. Builders restoring classic vehicles, fabricating custom hot rods, or upgrading suspension systems will find this wheel an excellent choice for enhancing performance and aesthetics.
