APEX ARC-8 17" Race Wheel

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.

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 work with smaller stock brakes, or smaller diameter big brake kits, but the larger kits will pose a major problem. The 17” ARC-8 has some of the best barrel-side BBK clearance, easily fitting most aftermarket 355mm kits.

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 4x100mm bolt pattern wheels feature a direct-fit 57.1mm center bore.

CENTER CAP
Maintain the OEM+ look

APEX center caps are included as standard. 4x100 BMW wheels never came with a nice-looking snap-in center cap. Not to worry, our 4x100-specific APEX center caps (included) are the exact diameter required to apply the OEM BMW stick-on roundel that was used with original E30 wheels.

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.
