Apex ARC-8 18x9 Flow-Formed Wheel 5x120 BP / ET30 / 72.56mm CB - Satin Bronze (BMW) (ARC8189ET30-5120-7256-SBZ)
The Apex ARC-8 has become one of the most recognizable BMW performance wheels thanks to its lightweight construction, race-proven durability, and timeless motorsport styling. This 18x9 ET30 version finished in Satin Bronze gives your BMW an aggressive track-inspired appearance while delivering the strength, brake clearance, and low rotational mass enthusiasts expect from a serious performance wheel.
Built using advanced flow-forming technology, the ARC-8 offers many of the structural advantages associated with forged wheels while maintaining a far more accessible price point. The barrel is strengthened during the manufacturing process to improve rigidity and durability, allowing Apex engineers to reduce unnecessary material and optimize weight without compromising strength. Extensive Finite Element Analysis testing further refines the design by reinforcing high-load areas and removing excess material wherever possible.

The ARC-8 was engineered around real-world motorsport use. Oversized lug recesses allow the use of race lugs and impact sockets, making wheel changes quick and hassle-free during track days and race weekends. The open hub center design further improves accessibility for enthusiasts who frequently swap between street and track setups.
Brake clearance was also heavily prioritized during development. The ARC-8 accommodates many popular aftermarket big brake kits while maintaining its signature deep-concave spoke profile. This allows BMW drivers to retain the handling advantages of lightweight 18 inch wheels while running larger braking systems capable of handling aggressive driving and repeated heat cycles.
