18" Staggered Wheel Set of 4 APEX ARC-8 wheels to suit E46 M3 (wheels only, tyres not included) These wheels look great with a classic BBS and "CSL" inspired design, and are built strong and light to perform on track and street. An OEM+ style bolt-on fitment that will not require additional modifications and is very unlikely to rub the fender liners, suspension components, etc. You'll gain some performance as well resulting from the wheels being lighter than stock, and the tires being slightly wider. These setups offer an improved stance, but not enough to require rolled fenders, compromises on tire size, or negative camber adjustments. These setups can be used for the occasional autoX and/or track day, but they won’t maximize performance as you'll be leaving a bit of wheel and tire width on the table for the sake of having an easy direct fitment. E46 M3 - OEM+ style staggered setup. 2 x Front 18x8.5" ET38 (APEX suggest use 235/40-18 tyres)2 x Rear 18x9.5" ET22 (APEX suggest use 265/35-18 tyres) Direct Fit Popular fitment 245/40-18 front and 275/35-18 rear tyres can also be used as a direct fit.

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 ProfileOne 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. SpokesMore 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 - SpokesSpokes 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 - BarrelA 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. Contact our experts to confirm brake clearances for your specific application. Open Hub CenterForm 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 CentricNo 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 CapA 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 HardwareOriginal 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 SensorsThey 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 FormingBenefits of forging, without the pain All APEX wheels including the ARC-8 wheel are produced using the Flow-Forming technique. 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 it's final shape. This effectively eliminates porosity and aligns the grain structure of the metal which increases tensile strength. The end result of the Flow-Forming process is a light-weight and extremely strong barrel that equals that of a traditional fully forged wheel at a fraction of the cost. Testing & CertificationsWe break a lot of wheels Computer simulated stress tests are no match for real world testing when designing a light-weight wheel that will see extreme loads. All APEX wheels are crush and load tested to exceed JWL standards and those results are independently tested in Japan by the 3rd party government agency known as the VIA. Countless wheel companies falsely claim they are tested and certified by the VIA, and so they lack the certificates to prove it. We test and certify each and every design, diameter, width, and offset, separately. We publicly list all our VIA registration numbers which are on file with the VIA for confirmation. Don't trust brands that claim testing, but can't provide verifiable registration numbers. Weight & Strength OptimizationIt’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. FinishesBecause 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. WarrantyA wheel you can depend on All APEX wheels are backed by a 2 year structural warranty and a 1 year finish warranty. This warranty guarantees that all APEX wheels will be free from defects in materials, workmanship, and paint finish under normal and reasonable use. APEX wheels are available in New Zealand from Autoform NZ Ltd, an authorized APEX dealer.
