Apex SM-8RS 17x9 Forged Wheel - 4x100 BP / ET45 / 54.1mm CB - Anthracite (SM8RS179ET45-4100-541-AN)
The Apex SM-8RS brings true motorsport engineering to the Mazda ND MX-5 Miata platform. As part of the Sprint Line family, this forged eight-spoke wheel takes inspiration from the popular SM-10RS while delivering exceptional strength, lightweight performance, and track-ready stiffness. Finished in Anthracite, the SM-8RS provides an aggressive appearance backed by race-proven durability and engineering.
Manufactured from forged 6061-T6 aluminum using an immense 10,000-ton forging process, the SM-8RS boasts a remarkable 1,400-pound load rating. That's over 230 pounds above JWL requirements and approximately 185 pounds stronger than many aftermarket ND Miata wheel options. Purpose-built motorsport blanks, extensive Finite Element Analysis, and the reinforced Sprint spec inner lip combine to create a wheel that excels on the street, autocross course, and road course alike.
