Apex SM-10 18x9 Flow-Formed Wheel - 5x130 BP / ET46 / 71.6mm CB - Satin Bronze (Porsche) (SM10189ET46-5130-716-SBZ)
The Apex SM-10 is a motorsport-inspired flow-formed wheel engineered for enthusiasts seeking lightweight performance, exceptional strength, and aggressive styling. Developed as part of the Apex Flow Formed Evolution Line, the SM-10 combines advanced engineering techniques with track-focused durability to create a wheel equally at home on the street or road course.
Finished in a rich Satin Bronze finish, this 18x9 SM-10 delivers optimized concavity, massive brake clearance, and reinforced structural integrity for demanding Porsche applications.
Flow Formed Evolution Technology
The SM-10 utilizes advanced flow-forming manufacturing technology to strengthen the barrel while minimizing unnecessary weight. This process improves the aluminums grain structure and mechanical properties, resulting in increased rigidity and impact resistance compared to traditional cast wheels.
Advanced I-Beam Spoke Engineering
One of the defining features of the SM-10 is its CNC-machined I-beam spoke design. Apex removes excess material from the sides of each spoke using precision ball-cutting technology, reducing rotational mass while maintaining exceptional structural strength.
Reinforced Inner Lip
The inner lip is one of the most vulnerable areas of any wheel. Apex reinforces this high-impact zone with additional material to improve resistance against potholes, track berms, and harsh road conditions.
Massive Brake Clearance
Through extensive laser scanning and real-world test fitting, Apex engineered the SM-10 to clear large factory and aftermarket brake systems that often require larger diameter wheels from competing manufacturers.
Weight Optimized Construction
Using extensive Finite Element Analysis (FEA), Apex reinforced high-load areas while removing unnecessary material throughout the wheel. The result is an exceptionally lightweight wheel without sacrificing durability or strength.
