The Apex SM-8RS brings true motorsport engineering to lightweight sports car applications with a forged eight-spoke design developed specifically around the demands of the Mazda ND MX-5 Miata platform. Part of Apex's Sprint Line, the SM-8RS delivers exceptional strength, low weight, and impressive stiffness for track enthusiasts and aggressive street drivers alike. Finished in Satin Bronze, this wheel offers race-inspired style backed by serious performance.
Manufactured from forged 6061-T6 aluminum using an immense 10,000-ton forging process, the SM-8RS boasts an outstanding 1,400-pound load rating. That's over 230 pounds stronger than required for JWL certification and roughly 185 pounds stronger than many aftermarket ND Miata wheel options.
