Apex SM-10 18x8.5 Flow-Formed Wheel - 5x130 BP / ET50 / 71.6mm CB - Race Silver (Porsche) (SM101885ET50-5130-716-RS)
The Apex SM-10 combines lightweight motorsport engineering, aggressive styling, and exceptional durability into a high-performance wheel package built for demanding Porsche enthusiasts. As part of Apexs advanced Flow Formed Evolution Line, the SM-10 delivers reinforced structural integrity, optimized weight reduction, and substantial brake clearance for both street and track applications.
Finished in a premium Race Silver coating, this 18x8.5 SM-10 offers a timeless motorsport-inspired appearance while delivering the strength and responsiveness expected from Apex Wheels. Advanced flow-forming technology, CNC-machined I-beam spokes, and FEA-optimized engineering work together to maximize performance without unnecessary mass.
Advanced Flow Formed Construction
Apex utilizes an advanced flow-forming process that improves barrel strength and rigidity while reducing wheel weight. This technology enhances the aluminum grain structure and mechanical properties, creating a stronger and lighter wheel compared to traditional cast designs.
CNC-Machined I-Beam Spokes
The SM-10 incorporates Apexs signature I-beam spoke machining process. Precision CNC ball cutting removes excess material from the spoke sides to reduce rotational mass while preserving the structural strength needed for aggressive driving environments.
Reinforced Inner Lip Design
The inner lip is one of the most vulnerable impact areas on any wheel. Apex strengthens this critical section with additional material to improve resistance against potholes, track berms, curbing, and harsh road conditions.
Massive Brake Clearance
Extensive laser scanning and repeated physical test fitting enabled Apex engineers to maximize brake clearance while maintaining lightweight 18-inch wheel sizing. The SM-10 clears many large factory and aftermarket brake systems that often require larger wheels from competing manufacturers.
FEA Weight Optimization
Finite Element Analysis (FEA) allowed Apex engineers to reinforce high-load areas while strategically removing material from low-stress zones. The result is a lightweight wheel that improves handling response, braking performance, and overall chassis dynamics.
