15x8 IMCA B/Lock Wheel Black D-Hole 5x4.75

The 15x8 IMCA B/Lock Wheel Black D-Hole 5x4.75 from BASSETT is a purpose-built racing wheel designed for oval-track competition and street rod applications that require lightweight, precision construction. IMCA (International Motor Contest Association) B/Lock wheels are specifically engineered for stock car racing, dirt track competition, and vintage hot rod builds where weight savings and bolt security are essential.

Constructed with a robust steel design, the 15x8 dimensions deliver a narrow profile that reduces unsprung weight while maintaining structural rigidity under lateral G-forces typical of racing scenarios. The D-hole mounting pattern (five-lug, 4.75-inch bolt circle) is a BASSETT standard that ensures secure wheel mounting on vehicles with traditional full-frame chassis and non-independent rear suspension geometry. The black finish provides a classic appearance while resisting corrosion and maintaining aesthetics through multiple seasons of competition.

At 27.83 lbs per wheel, this IMCA-spec design minimizes rotational inertia, directly improving acceleration response and braking performance—critical factors on tight oval tracks and autocross courses. This wheel is ideal for drivers competing in IMCA-sanctioned stock car divisions, nostalgia drag racing programs, and vintage hot rod builds where authenticity and reliability are paramount.
