Apex SM-10 18x9 Flow-Formed Wheel - 5x120 BP / ET30 / 72.56mm CB - Satin Black (BMW) (SM10189ET30-5120-7256-SMBK)
The Apex SM-10 is a lightweight flow-formed wheel engineered specifically for enthusiasts who demand true motorsport performance without sacrificing durability or daily drivability. Built as part of Apexs advanced Flow Formed Evolution Line, the SM-10 combines aggressive styling, optimized weight reduction, and track-ready strength into a wheel package trusted by performance drivers worldwide.
Finished in a stealthy Satin Black finish, this 18x9 SM-10 delivers aggressive concavity, massive brake clearance, and reinforced structural engineering designed to handle everything from spirited street driving to competitive track use.
Flow Formed Evolution Technology
The SM-10 utilizes advanced flow-forming manufacturing to strengthen the barrel while reducing overall weight. This process improves the aluminum grain structure and mechanical properties, resulting in a wheel that offers exceptional rigidity and durability compared to traditional cast wheels.
Advanced I-Beam Spoke Design
Apex machines excess material from the spoke sides using precision CNC ball-cutting technology to create its signature I-beam spoke profile. This process reduces rotational mass while maintaining the structural integrity needed for aggressive driving conditions.
Reinforced Inner Lip Construction
The inner lip is one of the most vulnerable impact areas on any wheel. Apex adds additional material to this critical zone to improve resistance against potholes, curbing, track berms, and harsh road conditions.
Engineered for Brake Clearance
Through extensive laser scanning and repeated physical test fitting, Apex engineered the SM-10 to clear many large factory and aftermarket brake systems that often require larger diameter wheels from competing manufacturers.
Weight Optimized Performance
Using extensive Finite Element Analysis (FEA), Apex reinforced high-load areas while removing unnecessary material from low-stress sections. The result is an exceptionally lightweight wheel that maintains outstanding strength and rigidity.
