ARC-8 Design

Fit Matters
The right solution for every application

An optimized car setup begins with the perfect wheel and tire fitment. Without model-specific attention to each wheels specifications, maximum performance is compromised. Each size was selected to find the right balance between a clean fit and the most grip possible. The ARC-8's wide range of widths, diameters, offsets and face profiles result in unique fitments ranging from 8" to 10.5" wide. Each wheel combines these features to meet the different brake caliper, strut, and fender clearance needs of each BMW model. Most vehicle models have options for wheels that range from direct-fit to aggressive for specialty applications. Daily drivers and professional racers don't have the same needs, so why should they be forced to buy the same exact fitment?

Face Profile
One design, many levels of beauty

The ARC-8 wheel is available in two unique face profiles. The shallower face provides increased caliper clearance on narrow applications, while the deeper concave face reduces weight and creates a stunningly aggressive appearance on low offset and wide width applications. These two face profiles are available in all 17", 18" and 19" diameters.

Spokes
More than just a pretty face

The spokes of the ARC-8 were designed to be robust where they need to be and extra lightweight where they can be. The split "Y" spokes were carefully evaluated from every aspect to ensure light weight and remarkable strength. The lack of a deep front lip and spokes that connect directly to the barrel's lip create a rigid wheel with even load distribution. These features help reduce one of the most common concerns with aftermarket wheels — bending. Beauty follows function with this extremely popular design, as it adapts perfectly to both flat and concave versions.

Brake Clearance - Spokes
Spokes that work for you

APEX wheels properly clear all OEM brake calipers. Our wheels are targeted at the serious performance-minded owner. The spokes of the flatter faced ARC-8 were designed to clear Big Brake Kits. This is the best and only choice for BBK equipped cars. The concave version of the wheel is the best option for cars with factory brake calipers. Contact our experts to confirm your specific fitment.

Brake Clearance - Barrel
A lot of room in a tight space

Spoke clearance is only half the problem. The barrel opening on a wheel also needs to be big enough to clear the sides of your caliper and rotor. Many wheels on the market have aesthetic compromises in their design that consumers don’t even know result in major negative impacts on barrel clearance. Those wheels may wor
