Flow Formed Evolution Technology
The SM-10 utilizes Apexs advanced flow forming process to improve barrel strength and rigidity while minimizing rotational weight. This manufacturing method enhances aluminum grain structure during production, delivering increased durability and performance compared to traditional cast wheel designs.
CNC-Machined I-Beam Spokes
One of the defining features of the SM-10 is its precision-machined I-beam spoke design. Apex removes excess material from low-stress areas while maintaining critical structural integrity, creating a wheel that is lightweight without sacrificing strength.
Reinforced Inner Lip Construction
The inner lip is one of the most vulnerable impact zones on any wheel. Apex adds additional reinforcement in this area to improve resistance against potholes, curbing, berm impacts, and rough track conditions.
Exceptional Brake Clearance
The SM-10 was engineered using laser scanning technology and extensive physical test fitting to provide impressive brake clearance for large factory and aftermarket brake systems. This allows enthusiasts to retain lightweight 18 inch wheel setups without compromising braking upgrades.
Weight Optimized Engineering
Extensive Finite Element Analysis was used throughout the SM-10 development process to reinforce high-load areas while reducing unnecessary material in low-stress zones. The result is improved steering response, sharper turn-in, and better overall chassis performance.
