Apex SM-10 18x8.5 Flow-Formed Wheel - 5x130 BP / ET45 / 71.6mm CB - Race Silver (Porsche) (SM101885ET45-5130-716-RS)
The Apex SM-10 delivers race-inspired engineering, lightweight performance, and aggressive styling for enthusiasts who demand more from their wheels. Built as part of Apexs advanced Flow Formed Evolution Line, the SM-10 combines reinforced structural strength with modern weight-saving technology to create a wheel equally suited for street driving, autocross, and track use.
Finished in a premium Race Silver coating, this 18x8.5 SM-10 offers a timeless motorsport appearance while delivering the durability and brake clearance expected from Apex Wheels. Utilizing advanced flow-forming technology, CNC-machined I-beam spokes, and FEA-optimized construction, the SM-10 is engineered to maximize performance without unnecessary weight.
Advanced Flow Formed Construction
Apex utilizes a proprietary flow-forming process to strengthen the wheel barrel while reducing overall weight. This manufacturing technique improves aluminum grain structure and increases rigidity, resulting in enhanced strength and impact resistance compared to traditional cast wheels.
CNC-Machined I-Beam Spokes
The SM-10 incorporates Apexs signature I-beam spoke machining technology. Excess material is carefully removed from the sides of each spoke using precision CNC ball cutting to reduce rotational mass while maintaining exceptional structural integrity.
Reinforced Inner Lip Strength
The inner lip is one of the highest-impact areas on any wheel. Apex adds additional reinforcement to this critical zone to improve resistance against potholes, track berms, curbing, and harsh road conditions.
Massive Brake Clearance
Extensive laser scanning and repeated physical test fitting allowed Apex engineers to maximize brake clearance within an 18-inch wheel design. The SM-10 clears many large factory and aftermarket brake systems that often require larger wheel diameters from competing manufacturers.
FEA Weight Optimization
Using advanced Finite Element Analysis (FEA), Apex reinforced high-stress zones while strategically removing material from low-load areas. The result is a wheel that delivers responsive handling, reduced rotational inertia, and outstanding durability.
