Spec-racing proportions meet street-legal fitment in the APEX SM-10RS, a forged 19x12 rear wheel sized to fill the widebody arches of 2005-2026 Mustangs without compromise on weight or structural integrity.
Forged construction at a real-world weight. At 21.3 lbs for a 19x12 wheel, the SM-10RS achieves a rotational mass figure that genuinely affects acceleration, braking, and steering feel. Forging refines the grain structure of the aluminum, producing a wheel that handles high-load cornering and track heat cycles without the bulk of a cast alternative.
Sprint Line geometry, dialed in for Mustang fitment. The SM-10RS belongs to APEX's Sprint Line family, a range developed around the dimensional requirements of serious track and performance street builds. The ET57 offset places the contact patch exactly where wide rear tires need it for predictable handling balance, and the 19-inch diameter clears the large-diameter brake packages common on S197 and S550 platforms.
Satin black finish for a track-focused aesthetic. The SM-10RS arrives in a satin black that resists the brake dust and heat cycles that degrade polished or gloss surfaces over time. The finish holds up in a paddock environment without demanding constant detailing attention.
