Forged construction at 18.7 lbs gives the APEX SM-10RS a weight advantage that pays dividends everywhere: quicker acceleration, shorter braking distances, and steering that responds to input rather than fighting inertia.
Sprint Line forged monoblock construction. APEX places the SM-10RS in its Sprint Line family, where every wheel starts as a forged blank and is machined to final dimensions. Forging aligns the grain structure of the alloy, producing a wheel that is both lighter and structurally stronger than a comparable cast unit.
18x10 ET40 dimensions suit the Mustang platform. The 18-inch diameter, 10-inch width, and 40mm positive offset were chosen specifically for 2005-2026 Mustang fitment across the S197 and S550 generations. This combination supports a wide range of street and track tire sizes without requiring spacers or fender modifications on most setups.
Satin black finish holds up to track use. The satin black coating resists the brake dust, heat, and cleaning chemicals that degrade glossy or polished surfaces over time, keeping the wheel looking consistent through repeated track days and daily commutes alike.
