APEX Wheels ARC-8RT Forged Wheel | 18×8.5 ET40 | 5×120

Description

The APEX ARC-8RT is a forged wheel from APEX’s Touring Line, engineered specifically for BMW applications utilizing the 5×120 bolt pattern. This 18×8.5 ET40 wheel addresses the performance demands of 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 ARC-8RT achieves a weight of 19 lbs in the 18×8.5 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.

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.

The ARC-8RT features Profile 1 face design, which provides the specific offset and spoke geometry optimized for BMW fitments. The 72.56mm center bore ensures proper hub-centric fitment for 5×120 BMW applications, eliminating vibration and ensuring precise wheel mounting. The 60 degree conical hardware seat is designed to work with BMW’s factory lug bolts and aftermarket wheel hardware designed for this seat type.
