Description
The APEX SM-10RS is a forged wheel from APEX’s Sprint Line, engineered specifically for BMW applications utilizing the 5×120 bolt pattern with 72.56mm center bore. This 18×10.5 ET22 wheel addresses the performance demands of BMW enthusiasts who require both strength and reduced unsprung weight for improved handling dynamics. The forged construction approach delivers superior material density and structural integrity compared to cast alternatives.
The SM-10RS achieves a weight of 19.2 lbs in the 18×10.5 configuration, representing a significant reduction in rotational mass that directly impacts acceleration, braking performance, and suspension response. This weight optimization is accomplished through the forged manufacturing process, which allows for precise material placement and thinner spoke sections without compromising structural strength required for high-performance BMW applications.
Forged construction utilizes a single piece of aluminum that is heated and formed under extreme pressure, creating a wheel with enhanced grain structure and material properties. This manufacturing method produces wheels that are both lighter and stronger than cast equivalents, making them suitable for high-performance driving applications where wheel failure is not acceptable. The forged process eliminates the porosity and inconsistencies found in cast wheels, resulting in a denser, more reliable structure capable of withstanding the demands of track use and spirited driving.
The SM-10RS features Profile 4 face design and utilizes 60 degree conical hardware seat for proper lug nut engagement. Multiple finish options are available including Anthracite, Brushed Clear, Satin Black, and Satin Bronze to complement various BMW styling preferences.
