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 8.5" 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.

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. Concavity is dependent on fitment, and not selected independently.

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
A lot of room in a tight space

Spoke clearance is only half the problem. The barrel construction on a wheel also needs to be big enough to clear the sides of your caliper and rotor. Many aftermarket wheels that have aesthetic compromises in their design may work with smaller stock brakes, or smaller diameter big brake kits, but the larger kits will pose a major problem. The barrel of the ARC-8 wheel offers unmatched caliper clearance because wheels shouldn’t limit your choice of aftermarket brake kits, and brake kits shouldn’t force you to run oversized wheels. We 2D modeled most Big Brake Kits available in Solidworks and tweaked the wheel design of the ARC-8 prior to production in order to fit as many kits as possible.

Open Hub Center
Easy to access lugs

Race wheels can't just be light, they need to function in a high performance environment. Unlike the narrow lug recesses of most other wheels, the ARC-8 wheel features a wide open hub center that easily accommodates oversized race lugs and beefy impact sockets. This allows for quick and easy wheel changes and prevents chips and scratches from tools.

Hub Centric
No rings or adapters here

All APEX ARC-8 wheels are purpose built for select vehicle applications, and centering rings are never required for any BMW application. All 5x120mm bolt pattern wheels feature a direct-fit, 72.56mm center bore.

Center Cap
A factory fit and finish

We don't reuse one cap design for all of our wheels. Every ARC-8 wheel is designed to work with factory center caps. You can easily replace APEX center caps with OEM roundels for a clean factory look. The ARC-8 wheels will ship with our Gloss Black center cap that mimics the size and shape of a BMW factory center cap.

Wheel Hardware
Original or Aftermarket, it all works

The ARC-8 wheel can be used with all OEM and aftermarket mounting hardware with a 60° tapered seat. Lug bolts, wheel locks, and stud conversion kits all work perfectly. The ARC-8 wheel also accepts wheel spacers without issue. The shallow rear chamfer allows the wheel to remain hub centric even when 5mm flat spacers are used. The chamfer is deep enough to clear the chamfered lip found on some aftermarket spacers that would typically cause improper seating of the wheel and, therefore, wheel vibration.

Flow Forming
Benefits of forging, without the pain

These APEX wheels are produced using a manufacturing process known as flow forming. This process significantly reduces weight in the barrel, which has the greatest impact on rotational mass. During the manufacturing process, rollers apply high pressure to the inner barrel, compressing the aluminum into its final shape. This effectively eliminates porosity and aligns the grain structure of the metal, which increases tensile strength. The end result is a lightweight and extremely strong barrel that equals that of a traditional forged wheel at a fraction of the cost.

Testing & Certifications
Verifiable 3rd party testing

Many companies promote their wheels as being certified by the VIA when they actually aren’t. That’s like using the USDA logo on food without permission. APEX wheels get officially tested and registered by the VIA in Japan, and we have the proof to back it up. Learn more about false VIA claims.

Japan’s JWL is a commonly followed standard for wheel load ratings. Our flow formed wheels meet, and most exceed, their load rating requirements. Most manufacturers only meet the minimum while some don’t even do that. Check and verify load ratings before you buy. Learn more about wheels that aren’t JWL.

Weight & Strength Optimization
It’s all in the details

Various design features were implemented to ensure that the ARC-8 wheel design was as light and durable as possible. We began with a strong one-piece design featuring an open hub center and reliefs in the mounting pad to remove weight between lug holes. The design was then run through Finite Element Analysis (FEA) to further optimize the spoke and barrel design. The result is a light weight wheel with extra strength in all the right places, while keeping weight to a minimum.

Finishes
Because being faster is just not enough

The ARC-8 wheel is available in multiple finishes, in addition to exclusive finishes available only through select dealers. All APEX wheels are finished using a comprehensive multi-stage liquid paint system over a powder coated base coat. Standard finishes include gloss metallic finishes, and semi-gloss or matte finishes. Hyper finishes include an additional coating of a premium liquid-like metallic silver to create a uniquely bright finish that can only be achieved through misting liquid paint.

Often overlooked, painted or powder coated lug hole seats can cause hardware to loosen or begin the spread of chipping the paint to more visible sections. The ARC-8 wheel's coating process leaves lug holes, center bores and mounting pads unpainted, which ensures proper fit and torque values.

Lifetime Warranty
A wheel you can depend on

As of recent, all our wheels now come with a lifetime structural warranty and 1 year finish warranty, so you can be confident in your purchase. See here for full terms and conditions.
