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 8.5" 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. 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 If the spokes of a wheel don't clear your brake calipers, then the wheel can't turn. We made sure the spokes on all 18" APEX wheels properly clear all OEM brake calipers, spacer free. Because of the large variation in clearance needs, APEX produced the ARC-8 wheel using two unique face profiles. When the correct profile is used for each specific vehicle application, most Big Brake Kits fit behind our 18" spokes, although a few applications will need a thin spacer due to the added width of aftermarket calipers. The flatter face profile offers maximum caliper clearance for high offset, narrow wheels, and older vehicles with Big Brake Kits. The deeper 18" concave face still has enough room to clear wider aftermarket Big Brake Kits on almost all applications, as we designed the spoke profile to require a thin spacer only in a few rare situations.

The barrel opening on a wheel also needs to be big enough to clear the sides of your caliper and rotor. Not all 18" wheels are made equal though. APEX designed the ARC-8's barrel to open to it's largest diameter as early as possible. The sooner this happens and the wider it opens, the larger the brake kit you can fit. This is vital on 18" applications because without enough clearance, most larger diameter brake kits will almost certainly not fit behind typical wheels. Most 18" wheels on the market make aesthetic compromises to their design that consumers wouldn't even know have a major negative impact on barrel clearance. Those wheels may work with smaller stock brakes, or smaller diameter Big Brake Kits, but the larger kits will pose a major problem. We 2D modeled most Big Brake Kits available in Solidworks and altered the wheel design to clear as many kits as possible. Our 18" ARC-8 wheels can clear some 380mm kits, and everything smaller clears the barrel with ease. Contact us to confirm brake clearances for your specific application. Open Hub Center Form follows function 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 boasts a completely wide-open design that easily fits over-sized race lugs and beefy impact sockets. This allows for quick and easy wheel changes at the track, and as a bonus prevents chips and scratches from tools for those just running these wheels on the street. Hub Centric No rings or adapters here All 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 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 wheel will come with either our carbon-look center cap or our redesigned, 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 some aftermarket spacers have that would typically cause improper seating and wheel vibration. TPMS Sensors They all fit TPMS sensors, which monitor tire pressure, are one piece of technology that can't be compromised. The attention to OEM compatibility on the ARC-8 wheel doesn't end with center caps. All APEX wheels accept OEM and aftermarket equivalent BMW TPMS sensors, and any standard sized metal or rubber valve stem. THE APEX STANDARD 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.
