► APEX | ARC-8 Lightweight 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 covers owners of all 5th and 6th Gen cars with direct fit solutions for their ride. Each wheel combines these features to meet the different brake caliper, strut, and fender clearance needs of each Camaro model.

2. Factory Support
Like all our APEX wheels, The ARC-8 supports all OEM hardware such as the OEM 6th Gen center cap, lug nuts, valve stems, and TPMS.

3. Brake Clearance
ARC-8 wheels properly clear all OEM brake calipers. Our wheels are targeted at the serious performance-minded owner. We were able to design the concave version of the wheel to clear the large ZL1 and Z/28 setups among with pretty much all known aftermarket kits as well.

4. Knurled Bead
We’ve upgraded these wheels to include a knurled bead seat to reduce unwanted tire rotation. This machined knurling throughout the wheel’s barrel increases friction between the wheel and tire to combat excessive tire slippage and maintain a true balance. Braking deep into a corner, bouncing off berms at the apex, and applying throttle at corner exit all apply enough tire load to cause unwanted tire slippage. Arrive at the track with balanced wheels and tires, leave the track with balanced wheels and tires.

5. Concavity
The Camaro ARC-8 wheel is available in the Profile 3 deep concave face which helps reduce weight and creates a stunningly aggressive appearance on each application.

6. Hub Centric
Our new lineup of Camaro specific wheels would not be complete without them being a true direct fit. All of these wheels feature a 67.1mm center bore, no centering rings required!

Designed for the Performance Enthusiast

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.

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 Camaro’s 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 the driver’s preference and consideration of tire costs. Every 5th and 6th Gen benefits from being able to fit both square or staggered setups with ease. Whether it is a street friendly 10” or track ready 10.5” square rotatable configuration, to a heavy performance minded 11” square setup, there is something for you to maintain neutral handling. For owners looking to squeeze the most wheel and tire possible under their car, the 19x11” front and 19x12” rear replicates the ZL1 1LE fitment and provides max effort grip for any platform.

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 big lug 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 lightweight 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 that 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.

Hi, we are anticipating the 19x12" wheels to be shipping out to customers in August.
