The ARC-8 is produced using the Flow-forming technique. Flow-forming, which has also been called 'spin forging', produces a barrel with similar strength to that of a fully forged wheel. This significantly reduces weight in the barrel, which has the greatest impact on rotational mass and performance. By combining the strength of a forged, lightweight barrel and a more robust face design, we've produced a wheel that welcomes endurance racing, hard driving, and even potholes.


ARC-8 Features & Benefits

Seventeen unique fitments in 17" and 18" sizes

  • Designed for spacerless fitment for most applications
  • Minimizes the requirement for spacers to achieve a perfect fit
  • Maximize wheel/tire width with model-specific fitments
  • 17" sizes reduce tire cost for track day wheels

Spoke design and barrel work together to create additional brake clearance

  • 17s have clearance for up to 355mm BBKs in many applications
  • 18s have clearance for up to 380mm BBKs in many applications

Mesh design

  • Load is more evenly distributed to reduce stress and enhance durability
  • Aesthetics aren't compromised to create strength

Lipless design

  • Maximizes strength in the most vulnerable area of the wheel
  • Greatly reduces bends and damage from small impacts

APEX ARC-8 wheels are JWL tested and VIA certified

  • Each size and fitment is tested and certified

Factory Fit

  • Designed for BMW applications, the ARC-8 accepts TPMS sensors, factory lug bolts or stud conversion kits, and OEM roundel center caps.
  • All wheels come with APEX center caps.

Open center

  • Easy lug access and reduced weight

Unpainted lug recesses

  • Prevents wheel bolts or lug nuts from loosening
  • Mounting wheels does not damage the finish

The ARC-8 is perfect for street, track, and race.
