Apex ARC-8 18x9 Flow-Formed Wheel 5x120 BP / ET30 / 72.56mm CB - Anthracite (BMW) (ARC8189ET30-5120-7256-AN)
The Apex ARC-8 has earned its reputation as one of the most respected BMW performance wheels on the market, and for good reason. Designed for drivers who demand lightweight performance, aggressive fitment, and track-proven durability, this 18x9 ET30 ARC-8 delivers the perfect balance of strength, brake clearance, and motorsport-inspired styling. Finished in Anthracite, this wheel gives your BMW a clean, purposeful look that works equally well on street-driven builds and dedicated track cars.
Built using advanced flow-forming technology, the ARC-8 offers many of the benefits of forged construction without the premium price tag. The barrel is strengthened through a specialized manufacturing process that improves grain structure and rigidity while reducing unnecessary weight. Apex then uses extensive Finite Element Analysis testing to strategically reinforce high-stress areas and remove excess material where it is not needed. The result is a lightweight wheel engineered to handle aggressive driving, repeated track abuse, and demanding big brake setups with confidence.

Why the ARC-8 Continues to Dominate BMW Performance Builds
The ARC-8 was engineered with real-world motorsport functionality in mind. Unlike wheels designed primarily for appearance, every detail of the ARC-8 serves a performance purpose. The open hub center allows for rapid wheel swaps at the track, while oversized lug recesses accommodate race lugs and impact sockets without the frustrations commonly associated with tuner-style wheels.
Apex also maximized brake clearance by carefully engineering both spoke and barrel geometry. Many large brake kits fit comfortably behind the ARC-8 without requiring oversized wheels, helping drivers maintain lower rotational mass and sharper handling response. The deep concave spoke profile gives the wheel an aggressive stance while preserving the strength and clearance required for serious driving.
