A FITMENT FOR YOU

Need help selecting the proper wheel fitment for your BMW? APEX Race Parts have tirelessly test-fitted hundreds of setup combinations in order to provide direct-fit, spacer-free wheel packages for everything from showroom-fresh cars to all-out race builds. Their detailed fitment guides help you avoid costly trial-and-error and walk you through every step of finding your perfect setup.
Fit Matters

The right solution for every application

An optimized car setup begins with the perfect wheel and tyre 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 8.0" 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. APEX 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 the 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 APEX designed the spoke profile to require a thin spacer only in a few rare situations. Contact us to confirm brake clearances for your specific application.

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. 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. APEX 2D modeled most Big Brake Kits available in Solidworks and altered the wheel design to clear as many kits as possible. The 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 Centre
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 centre bore.

Centre Cap
A factory fit and finish

APEX don't reuse one cap design for all their wheels. Every ARC-8 wheel is designed to work with factory centre caps. You can easily replace APEX centre caps with OEM roundels for a clean factory look. The ARC-8 wheel will come with either a carbon-look centre cap or the redesigned, Gloss Black centre cap that mimics the size and shape of a BMW factory centre 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 tyre 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 centre 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.

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 they have the proof to back it up.

Japan’s JWL is a commonly followed standard for wheel load ratings. The APEX 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.

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. APEX began with a strong one-piece design featuring an open hub centre 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, centre bores and mounting pads unpainted, which ensures proper fit and torque values.

Warranty
A wheel you can depend on

APEX wheels now come with a lifetime structural warranty and 1 year finish warranty, so you can be confident in your purchase.

          Good quality office chair with movable arms
          Color: Dark, Color: Dark
          This chair was relatively easy to put together. After unboxing and laying out all of the parts, my husband and I built it in 22 minutes. We noticed how the instructions have you put the tilt mechanism bracket on after putting the back and arms on. Another chair we built was the opposite, which made attaching it to the base actually easier. That way just made more sense. This way, you put the back and seat together using the arms, then you attach the tilt mechanism to the bottom of the seat, but the seat is at an angle when you do this. Then you lift the whole chair and place it down onto the legs. I'm glad there were two of us to do that part. We also noticed one of the holes for screwing in the arm bracket was not lined in metal like the rest of them were. It still worked, though. It does rock a bit back and forth. The height adjusting rod also locks the chair in place for when you don't want the chair to lean back. There is a knob underneath that allows you to loosen or tighten how much it moves when you lean back or rock. The material is faux leather. It looks like real leather and feels pretty good. This makes it easy to clean. The arms can be raised level with the back of the chair to make it easy to slide out of the side of the chair. Overall this chair has a pretty classic look to it and is comfortable to sit in. It even has some lumbar support. The way the back of the chair and the seat of the chair connect together leaves a little bit of a gap. Nothing major, but you could lose coins or keys through the gaps between the cushions. If you have a cat, this would be a great way for them to poke their paws through and say hello.

          Nice office chair!
          Color: Dark
          This is a nice office chair. All of the features work as stated. I would say the seat is slightly more firm than I prefer, but comfort is subjective. The pleather is soft and I like that the arm rests fold out of the way.

          This Marsail Executive Office Chair Is Excellent For A Comfortable And Polished Desk Setup
          Color: Dark
          This Marsail executive office chair is excellent, and it brings together comfort, support and a clean professional look in a very practical way. The PU leather has a smooth, polished presence that suits a desk chair well without looking overly bulky. I appreciate that the design includes flip-up armrests, a height-adjustable seat, swivel movement and rolling mobility in one complete chair. The cushioning gives the chair a substantial seated feel, while the back design adds support without making the chair look heavy. It is an office chair that feels thoughtfully built for daily desk work, focused tasks and general seated comfort. The chair arrived securely protected and in very good condition, with the main parts kept in place well through transit. The PU leather surfaces looked clean, smooth and free from distracting marks when unpacked. The base, wheels, armrests, backrest and hardware all appeared properly finished and ready for assembly. Nothing about the chair parts looked loose, flimsy or poorly handled when it arrived. The included components were organized. The appearance of this chair is one of its strongest qualities because it has a dark, sleek and professional style. The chair fabric gives it a refined executive look, while the breathable mesh center keeps the backrest from appearing too solid or oversized. The flip-up armrests blend into the design nicely and add a cleaner profile when raised. The chair has a balanced shape, with a supportive back, plush seat and wide base that all work together visually. It looks modern without being too flashy, which makes it easy to place with different desks and work areas. Functionality is where this chair becomes especially practical because it is easy to put together and simple to adjust. The height adjustment works well for getting the seat into a comfortable position at a desk. The swivel and rolling movement make it easy to shift, turn and reach without the chair feeling stiff. The reclining range and gentle rocking function add a useful option for leaning back during breaks. The flip-up armrests are especially convenient because they allow the chair to tuck under a desk more easily and create extra freedom of movement when needed. The value is strong because this chair offers several useful features in one well-rounded design. The thicker cushioning, contoured support, PU leather surface, breathable backrest, reclining function and flip-up armrests all add to its usefulness. The sturdy base and stated 300-pound support rating also give it a more dependable feel than a basic desk chair. It provides the comfort expected from an executive chair while still offering space-saving details that make it practical. For the features, comfort and overall build, it delivers a very complete office seating option. I highly recommend this Marsail executive office chair for anyone wanting a comfortable, polished and functional desk chair. It is excellent, easy to put together and built with enough adjustability to support different work habits. The combination of plush cushioning, ergonomic shaping, smooth movement and flip-up armrests makes it especially useful for a home office or workspace. I also like that it has a professional look without sacrificing everyday convenience. It is a strong choice for dependable seating that looks good, works well and offers solid comfort.

          Comfortable for daily use!
          Color: Dark, Color: Dark
          After using this chair for work and general desk time, I think it does a nice job balancing comfort, adjustability, and overall build quality without feeling overly bulky or cheap. It feels designed for people who spend long stretches at a desk and want something supportive but still comfortable enough to relax in occasionally. Assembly was straightforward. The instructions were clear, the hardware was organized well, and all the holes lined up properly during setup. I put it together by myself in around 20 minutes without needing extra tools. Once assembled, the chair immediately felt sturdy and stable rather than wobbly. The overall quality is solid for this price range. The PU leather has a soft feel and doesn’t have the stiff plastic-like texture some office chairs use. The stitching looks clean, the armrests feel secure, and the rolling base moves smoothly across the floor. The chair also feels durable overall, especially around the frame and base where cheaper chairs sometimes feel weak or shaky after a few weeks of use. It's very comfortable. The seat cushion is thick and supportive without feeling overly hard, and it stays comfortable during long work sessions. I’ve spent multiple hours at a time sitting in it without constantly adjusting positions or feeling pressure points. The mesh section in the backrest also helps airflow a bit, which keeps it from feeling too hot during extended use. The lumbar support is great. The backrest naturally follows the curve of your spine and provides good lower back support while still feeling relaxed enough for casual sitting. I also liked the higher back design since it supports the upper back and shoulders well during longer periods at the desk. The flip-up armrests ended up being more useful than I expected. They make it easy to slide the chair under the desk when not in use, and they also give more room if you like sitting cross-legged occasionally. Solid chair overally. It has a good mix of comfort, support, ease of use, and practical features without feeling overpriced.
