Spec-led: At 21.3 lbs in a 19x12 forged construction, the APEX SM-10RS delivers the kind of corner-weight savings that show up in lap times, not just on a spec sheet.
Forged construction at a competition-relevant weight. The SM-10RS is forged, not cast, which concentrates material where the structure demands it and removes it everywhere else. The result is a 19x12 wheel that comes in at 21.3 lbs, reducing unsprung and rotating mass at all four corners.
Sprint Line engineering for the S197 through S650 platform. The SM-10RS belongs to APEX's Sprint Line family, a lineup developed specifically for track-focused Mustang builds. The ET57 offset on this 19x12 fitment positions the wheel correctly within the rear fender envelope of 2005-2026 Mustangs, supporting aggressive rubber fitment without rubbing or spacer stacks.
Anthracite finish suits function and appearance equally. The anthracite finish resists brake dust and heat discoloration better than polished or bare metal surfaces, so the wheels look presentable after a hard session without requiring excessive detailing.
