Apex SM-10 18x9 Flow-Formed Wheel - 5x112 BP / ET42 / 57.1mm CB - Race Silver (Audi - Small Bore / Volkswagen) (SM10189ET42-5112-571-RS)
The Apex SM-10 is a lightweight flow-formed wheel engineered for enthusiasts who demand motorsport-level strength, aggressive styling, and optimized performance. As part of Apexs advanced Flow Formed Evolution Line, the SM-10 combines cutting-edge engineering with track-proven durability for street and competition applications alike.
Finished in a brilliant Race Silver finish, this 18x9 SM-10 delivers aggressive concavity, impressive brake clearance, and reinforced structural integrity designed to withstand both spirited driving and demanding track conditions.
Flow Formed Evolution Technology
The SM-10 utilizes advanced flow-forming manufacturing technology that strengthens the barrel while reducing unnecessary weight. This process improves the aluminums grain structure and mechanical properties, creating a wheel with superior rigidity and impact resistance compared to conventional cast wheels.
Advanced I-Beam Spoke Engineering
Apex machines excess material from the sides of the spokes using precision CNC ball-cutting technology to form its signature I-beam spoke profile. This technique lowers rotational mass while preserving the structural integrity required for high-performance driving.
Reinforced Inner Lip Design
The inner lip is one of the most vulnerable sections of any wheel. Apex reinforces this critical area with additional material to improve resistance against potholes, curbing, track berms, and harsh road conditions.
Massive Brake Clearance
Through extensive laser scanning and repeated test fitting, Apex engineered the SM-10 to clear many large factory and aftermarket brake systems that often require larger wheels from competing brands.
Weight Optimized Construction
Using advanced Finite Element Analysis (FEA), Apex strategically reinforces high-load zones while removing material from low-stress areas. The result is a wheel that remains exceptionally lightweight without compromising strength.
