Apex ARC-8 18x9 Flow-Formed Wheel 5x120 BP / ET30 / 72.56mm CB - Hyper Black (BMW) (ARC8189ET30-5120-7256-NHBK)
The Apex ARC-8 has become a staple in the BMW performance world thanks to its lightweight construction, aggressive fitment options, and proven durability on both the street and the track. This 18x9 ET30 configuration finished in Hyper Black combines motorsport-inspired styling with race-ready engineering, giving BMW enthusiasts a wheel that performs as aggressively as it looks.
Manufactured using advanced flow-forming technology, the ARC-8 strengthens the barrel structure while reducing unnecessary mass to create a wheel that offers exceptional rigidity and durability without the cost of full forging. Apex engineers utilized extensive Finite Element Analysis testing to strategically reinforce high-stress areas while removing excess material where it provides no strength benefit. The result is a lightweight, deep-concave wheel capable of handling aggressive driving, track use, and demanding brake setups with confidence.

Track-Tested Engineering with Aggressive BMW Styling
Every detail of the ARC-8 was developed with real-world motorsport functionality in mind. The oversized lug recesses allow the use of impact sockets and race lugs, making wheel swaps faster and easier during track events or pit lane changes. An open hub center further improves accessibility for drivers who frequently switch between street and track wheel setups.
Brake clearance was also a major engineering priority. The ARC-8 accommodates many popular aftermarket big brake kits while maintaining its signature deep-concave spoke profile. This allows BMW enthusiasts to retain lightweight 18 inch wheel performance while still running larger braking systems for improved stopping power and thermal control.
