The Flow Form Advantage
Flow forming enables us to create high performance wheels without the price premium of forging. It improves the mechanical properties and grain structure of the barrel, increasing its strength and stiffness, which allows us to use less material and reduce weight. Thanks to our superior engineering, our flow formed wheels have a higher load rating than some competitors' forged wheels.
Big Brake Clearance
Big brakes often require bigger, heavier, more expensive wheels, which aren't ideal in a performance environment. The ARC-8 accommodates many big brake kits, even with its classic deep-concave spokes. If you need more clearance, the forged ARC-8R or one of our curved spoke wheel designs has you covered.
Maximizing Concavity
We use the deepest concave face profiles we can for every application after factoring in critical clearances such as brake calipers. The ARC-8 utilizes 2 unique profiles to make this possible, with the deepest concave face delivering reduced weight and a stunningly aggressive appearance.
Weight Optimized
We conducted extensive Finite Element Analysis (FEA) to reinforce high-stress areas and to remove material where it didn't improve strength. The result is a wheel that is exceptionally light without the strength compromises found on typical lightweight wheels.²
Built for Impact Sockets
Track wheels need track tools. Don't settle for wheels that require undersized tuner lugs or thin walled sockets. All APEX wheels accommodate over-sized race lugs and impact sockets to make swapping wheels lightning fast.

Socket Diameter Clearance
Finishing Touches
The ARC-8 is finished using a multi-stage liquid paint over a powder coated base coat. This coating process leaves lug holes, center bores and mounting pads untouched, which ensures proper fit and torque values.
JWL and Beyond
All APEX Flow Formed wheels meet or meaningfully exceed JWL load rating requirements. Some manufacturers don't meet the minimum requirements, yet still claim to be compliant. Always compare load ratings to ensure you aren't sacrificing critical strength for a slightly lighter wheel.
True VIA
The VIA is an independent wheel testing and auditing agency similar to TÜV. Many companies falsely claim their wheels have been certified, and even use the VIA stamp without permission. Our Flow Formed wheels have been certified, and we provide the registration numbers for every wheel. Protect yourself. Demand registration numbers from manufacturers.
Additional features
Hub Centric
All ARC-8 wheels are purpose built for select vehicle applications. Very few applications require centering rings.
Center Caps
All APEX wheels come with our gloss black cap included that is interchangeable with the OE cap. We also offer additional colors for select fitments.
Wheel Hardware
APEX wheels can be used with all OEM mounting hardware, proper aftermarket hardware and most wheel spacers. Wheel locks and stud conversion kits also work perfectly.
TPMS
All APEX wheels accept OEM and aftermarket Tire Pressure Monitoring Sensors and standard fit valve stems. If you don't have sensors, then select from our metal stems available in multiple finishes.
