Spec-1 Wheels SP-731883538GBRU SP-73 18x8.0 Gloss Black & Red Undercut Wheel 5x110 5x114.3 +38mm

The Spec-1 SP-73 is a cast aluminum aftermarket wheel that blends a contemporary multi-spoke design with bold two-tone styling. This 18x8.0 variant is finished in a striking gloss black with red undercut accents, giving it an aggressive, sport-forward appearance that stands out from the factory look.

Constructed from aluminum, the SP-73 delivers an excellent balance of strength and reduced unsprung weight. A protective clear coat is applied over the finish to guard against the wear of daily driving, helping maintain the wheel's appearance over time. The dual bolt pattern — 5x110 and 5x114.3 — provides broad compatibility across a wide range of passenger cars and sport compacts.
