Default ► APEX | ARC-8 Light Weight Track Wheels





APEX ARC-8 Wheels

We are proud to continue offering our timeless ARC-8 wheel. This new wheel addresses the concerns of more and more racers and track day enthusiasts: long term durability, fitment, and performance. With the increase of faster and heavier cars being used in racing, HPDEs, and spirited driving, the ARC-8 was designed and engineered to handle extreme abuse on track and street, offer a wide range of direct fitments, while still producing a lightweight wheel.

Visit our website to order



The Good Stuff



1. They Fit Everything
The ARC-8's wide range of widths, diameters, offsets and face profiles result in 26 unique BMW 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.

2. Factory Support
Like all our APEX wheels, The ARC-8 supports all OEM hardware like OEM Roundel center caps, wheel lugs, valve stems, and TPMS sensors. No centering rings are needed either, as all of our 5x120 BMW wheels use a 72.56mm center bore.

3. Brake Clearance
ARC-8 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, making it a better choice for BBK equipped cars. The concave version of the wheel is the best option for cars with factory brake calipers.

4. Concavity
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.



Designed for the Performance Enthusiast

Light-weight
Flow-forming allows for a significant reduction in rotational mass by reducing barrel weight. This manufacturing technique allows our wheels to be almost as light as a traditional forged wheel, but without the significant increase in price.

Strength
Track duty requires a wheel that can handle the punishment of high lateral G's, hitting berms, and every once in a while, a small off track excursion. Spoke and barrel design are a major factor in wheel strength. The flow-forming technique uses high pressure disks/rollers to roll the wheel's barrel into its final shape. This gives the barrel the same strength properties as a forged wheel, since monoblock wheels go through a similar step to form their barrels. We design our spoke dimensions to help evenly distribute loads from the barrel to the center of the wheel. The lack of a front lip, and spokes directly connecting to the edge of the wheel, also add increased strength to the outer lip of the wheel.

Chassis-Specific Fitments
Stretched rubber, narrow tires, and fender rubbing are not elements to look for in a competitive wheel/tire setup. All of our wheels were designed with offsets that allow for proper fitment of extreme summer, and r-compound tires without the need for spacers or fender rolling. This means keeping the tire under the fender, and away from suspension components. Track oriented wheel widths are also important as they provide proper sidewall support under hard cornering. Too much rubber for a wheel results in excessive sidewall deflection, which translates into sloppy and delayed turning response.

Multiple Fitment Options
Most BMWs come with a staggered setup from the factory. Some choose to keep their car this way, while others like to switch out for an easy-to-rotate, square/neutral setup. This is generally based on driver's preference and consideration of tire costs. Most BMW chassis benefit from being able to fit both square and staggered setups with relative ease. 9.5" or 10"-wide square setups are great for budget minded enthusiasts who want to extend their tires life by rotating between events, in addition to preferring the feel of a square setup. Square setups are popular on all models for track use due to the significant increase in front grip and turn-in response. Some owners comment that due to the extra power of their cars, a square setup will lean towards oversteer. For those who prefer more rubber in the rear, a staggered setup is the way to go. Wheels up to 10.5" wide are available for rear fitment. These can be combined with 9" or 9.5" fronts for a bolt-on spacer-free staggered setup.

Open-Hub Center
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.




The APEX Standard



1. FEA Optimization
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.

2. Always Flow Formed
All APEX wheels feature Flow-Formed construction tha utilizes rotary forging to produce a strong and lightweight barrel. The ARC-8 is no exception.

3. True JWL & VIA Certification
Strength needs to be certified. Our wheels were not simply FEA tested in a computer simulation, or in-house tested to an unregulated standard. We conduct real-world crush-testing and all of our wheels conform to Japan's JWL standard, as well as being 3rd-party tested by the VIA. All of our wheels carry a 690KG load rating.

Still in the process of deciding on square or staggered.

I'd like to get a 18x9.5" square set up without having to run more than -2 degrees of camber up front. Is there a set (Et22, ET35, or combo with spacers in rear) that will work? I plan to use 265/35/18 tires.

ET 22's with this size will require more camber based on my experience....at least -3.0 in the front with "rolled" fenders and evening loosening the fenders and pulling them out. That's what I have to do. BFG R1 dot slicks 265/35 18. The ET 22s are perfect in the rear with this tire size.

I just bought a set of the new EC-7s with 35 offset and Hankook Z214 275s all around...I am using a 12 mm spacer in the rear and they fit perfect.

The ARC-8's do have the ability to fit over a Stoptech 380mm big brake kit! The front wheels that would be able to fit over this kit are the 18x9.5" ET22 and the 18x10" ET25.

We look forward to it! You know who to reach if you have any fitment or availability quesitions.

Our 18x9.5" ET35 is a much easier fit in the front of an E46 M3 compared to some of the other 18x10" and lower offset 9.5" offerings. Depending on the type of tire you plan on using it can be close but with about -2 degrees of camber it is possible. A tire that runs larger than other street tires like an R compount or extreme performance summer tire like the Hankook RS3 or Dunlop Star Spec can have the possibility of rubbing. Make sure the alignment pins are pulled on your stock strut mounts and you have them adjusted all the way in for more camber. Most people will also use a 12-15mm spacer in the rear to fill out the fender a little bit more for aesthetic purposes as well as a wider track width.

Thanks for the reply. I have a new set of 265/35/18 Pilot Super Sports that I plan to run with these wheels (e.g., 18x9.5" ET35). Can you confirm that these will not rub in the front with -2 degree camber? If all is well, I'm ready to order a set of wheels, rear spacers, and a stud conversion kit. Please let me know!

Is there any possibility of a holiday sale? Black Friday or just a holiday season sale?
Or maybe an upcoming group buy?
