15x8 IMCA Silver Inertia 5x4.75

The Bassett 15x8 IMCA Silver Inertia wheel is a purpose-built competition wheel engineered for high-performance off-road racing and rally applications. With a 4.00-inch backspace and 5x4.75-inch bolt pattern, this wheel is optimized for vehicles requiring precision fitment and weight-critical performance in sanctioned IMCA events and similar motorsport disciplines.

Constructed from steel with a durable silver powder-coat finish, the Bassett 15x8 IMCA wheel delivers the structural rigidity demanded by competitive racing while resisting corrosion and maintaining visual appeal through extended racing seasons. The 20.8-pound weight reflects the engineering balance between strength and rotational inertia reduction—critical factors in acceleration and fuel efficiency during endurance racing. The 4.00-inch backspace provides the offset geometry necessary for proper brake clearance and suspension geometry in IMCA-legal builds, while the 5x4.75-inch bolt pattern accommodates the specific hub configurations common to vintage and modern competition chassis.

This wheel is designed for racers and competitors running IMCA-sanctioned events, including dirt track racing, short-track oval competition, and vintage off-road rally applications. The 15-inch diameter is standard for compact, lightweight competition setups where reducing unsprung weight directly improves handling response and braking performance. The silver powder coat provides a professional appearance while maintaining the durability expected in high-stress motorsport environments where wheels endure repeated impacts, lateral loads, and exposure to track dust and moisture.
