The Apex ARC-8 has earned legendary status among BMW enthusiasts by delivering lightweight performance, aggressive styling, and track-ready durability in one proven package. This 18x9 ET42 version finished in Hyper Silver combines timeless motorsport aesthetics with the strength, brake clearance, and responsive handling characteristics serious drivers demand from a true performance wheel.
Built using advanced flow-forming technology, the ARC-8 strengthens the barrel structure to improve rigidity and impact resistance while reducing unnecessary material for optimized weight savings.

Purpose-Built for BMW Street and Track Performance
The ARC-8 was engineered with real-world motorsport functionality in mind. Oversized lug recesses allow the use of impact sockets and race lugs, making wheel swaps faster and easier during track days and race events. The open hub center design further improves accessibility for enthusiasts who regularly switch 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 concave spoke design. This allows BMW enthusiasts to run larger braking systems while preserving the handling and responsiveness advantages that come from lightweight 18 inch wheels.
