Apex SM-10RS 18x11 Forged Wheel - 5x112 BP / ET40 / 70.3mm CB - Anthracite (BMW) - SM10RS1811ET40-5112-666-AN
The Apex SM-10RS was engineered for drivers who demand uncompromising performance from every component on their BMW. Finished in a motorsport-inspired Anthracite finish, this 18x11 forged wheel combines aggressive styling with cutting-edge engineering to create a lightweight wheel that thrives on both the street and the track. Designed as part of Apexs Sprint Line, the SM-10RS delivers exceptional stiffness, massive brake clearance, and reinforced durability without unnecessary weight.
Built using proprietary 6061-T6 forged aluminum blanks compressed under an immense 10,000 metric tons of pressure, the SM-10RS achieves superior strength and structural integrity. Apex optimized every detail through extensive Finite Element Analysis, allowing material to be removed where unnecessary while reinforcing critical stress zones. The result is a wheel that remains incredibly lightweight while offering outstanding rigidity, enhanced impact resistance, and track-proven durability for high-performance BMW applications.
