Forged construction at 18.7 lbs keeps unsprung mass low across the full 2005-2026 Mustang lineup, and the SM-10RS Sprint Line delivers that weight savings without sacrificing the structural integrity a track day or canyon run demands.
Forged for real performance gains. Forging densifies the aluminum grain structure, producing a wheel that handles cornering loads and curb strikes far better than a cast alternative at comparable or greater weight. At 18.7 lbs in an 18x10 ET40 fitment, the SM-10RS sits at a competitive point for a wheel this wide.
ET40 offset fits the S197, S550, and S650 without rubbing. The 40 mm positive offset places the contact patch correctly within the Mustang's front and rear fender geometry across all three modern generations. That precision fitment means no spacers, no fender rolling, and no guesswork on clearance.
Satin Bronze finish suits both stock and modified Mustangs. The muted metallic tone of Satin Bronze complements factory color palettes from Vista Blue to Dark Highland Green while standing apart from the ubiquitous silver or gloss black options on the market. The satin texture also hides brake dust and minor surface contamination better than a polished finish.
Sprint Line heritage means track-first engineering. APEX built the Sprint Line around road course and autocross use, so the SM-10RS face geometry, spoke section, and barrel wall thickness all reflect the demands of repeated high-load cornering rather than static display.
