15 X 4in. Pro Star 5 X 4.5in. 1.875in. BS

The 15 X 4in. Pro Star 5 X 4.5in. 1.875in. BS wheel from Weld Racing is engineered for serious performance-minded drivers who demand precision, strength, and motorsport-grade reliability. Built with a 15-inch diameter and 4-inch width, this wheel delivers the lightweight advantages needed for track duty, autocross, or high-performance street builds where every tenth of a pound matters.

The Pro Star design has been a fixture in competition circles for decades, trusted by drivers who refuse compromises on wheel integrity under extreme cornering loads and sustained lateral forces. What sets this Weld Racing wheel apart is its 5 x 4.5-inch bolt pattern compatibility and 1.875-inch backspacing geometry, which allows precise fitment tuning for suspension geometry optimization and brake clearance management.

At 14.3 pounds per wheel, this is genuine competition-spec hardware that shaves unsprung weight without sacrificing the structural rigidity required for aggressive cornering or emergency avoidance maneuvers. The 5 x 4.5-inch bolt circle makes this wheel ideal for classic American muscle platforms, vintage race cars, and period-correct restorations where OEM fitment is non-negotiable.
