Apex SM-10 18x9 Flow-Formed Wheel - 5x112 BP / ET42 / 57.1mm CB - Satin Black (Audi - Small Bore / Volkswagen) (SM10189ET42-5112-571-SMBK)
The Apex SM-10 is a motorsport-inspired flow-formed wheel engineered for enthusiasts who demand lightweight performance, aggressive styling, and exceptional durability. Designed as part of the Apex Flow Formed Evolution Line, the SM-10 delivers track-ready strength with advanced engineering features typically reserved for premium forged wheels.
Finished in a stealthy Satin Black finish, this 18x9 wheel offers aggressive concavity, massive brake clearance, and reinforced structural strength for high-performance Audi and Volkswagen applications.
Flow Formed Evolution Technology
The SM-10 utilizes advanced flow-forming manufacturing technology to improve barrel strength while reducing overall wheel weight. This process enhances the aluminums grain structure and mechanical properties, allowing Apex to create a wheel with impressive rigidity and impact resistance without the cost of a fully forged wheel.
Advanced I-Beam Spoke Design
Apex machines excess material from the sides of each spoke using precision CNC ball-cutting technology to create its signature I-beam spoke profile. This advanced machining process minimizes rotational mass while maintaining the strength needed for aggressive street and track use.
Reinforced Inner Lip Construction
The inner lip is one of the most vulnerable sections of a wheel during impacts. Apex reinforces this area with additional material to provide enhanced durability against potholes, curbing, and harsh track conditions.
Engineered for Big 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 typically require larger and heavier wheels from competing brands.
Lightweight Performance
Finite Element Analysis (FEA) was used extensively during development to strengthen high-load areas while eliminating unnecessary material. The result is a wheel optimized for reduced rotational mass without compromising durability.
