Apex ARC-8 18x9 Flow-Formed Wheel 5x120 BP / ET30 / 72.56mm CB - Satin Black (BMW) (ARC8189ET30-5120-7256-SMBK)
The Apex ARC-8 remains one of the most respected performance wheels in the BMW community, offering a proven combination of lightweight construction, aggressive fitment, and race-ready durability. This 18x9 ET30 configuration finished in Satin Black delivers a clean, stealth-inspired motorsport appearance while maintaining the strength, brake clearance, and low rotational mass demanded by serious enthusiasts.
Constructed using advanced flow-forming technology, the ARC-8 achieves many of the performance advantages associated with forged wheels without the premium price tag. The manufacturing process strengthens the barrel structure to improve rigidity and impact resistance while reducing unnecessary material for optimized weight savings. Apex engineers further refined the wheel using extensive Finite Element Analysis testing to reinforce high-load areas while eliminating excess material that does not contribute to strength.

Race-Proven Performance for BMW Enthusiasts
The ARC-8 was engineered around real-world motorsport functionality. Oversized lug recesses allow the use of impact sockets and race lugs, making wheel changes significantly easier during track days and competition events. The open hub center design further improves accessibility for enthusiasts who regularly rotate between street and track wheel setups.
Brake clearance was also heavily prioritized during development. The ARC-8 accommodates many aftermarket big brake kits while maintaining its signature deep-concave spoke design. This allows drivers to retain the handling and response benefits of lightweight 18 inch wheels while running larger braking systems designed for aggressive driving and repeated high-temperature use.
