If you're in the market for wheels for your street, track, or race car look no further than Apex Wheels. The ever-popular ARC-8 wheel is now offered in a forged wheel option as the ARC-8R. Forged wheels offer superior strength and durability over traditional flow-formed wheels. For example, the 17x8.5" ARC-8 flow-formed wheel has a load rating of 1450lbs vs the 1700lbs rating of the ARC-8R forged wheel.

Apex Wheels have been around for quite some time now and offer the perfect balance between strength, weight, and cost. These wheels are proven many times over on racetracks across the country and around the world.

With countless sizes, offsets, models, and colors available you are sure to find something for your car that meets your fitment and style. We have been running Apex Wheels on our heavy Hinz Motorsport M3 test vehicle for several years now without any issues despite countless excursions over potholes and race track curbing. These wheels are lighter than stock and certainly look the business.

In addition to all of the aforementioned attributes, APEX Wheels offer superb brake caliper clearances for those running big brake kits. In addition to FEA performed on each wheel design, extensive 3rd party testing is also conducted on every wheel shape and size to ensure that the wheels exceed all safety standards. Simply put, these wheels are certifiably strong and will withstand abuse so that you can buy with confidence.

These are all just a few reasons why APEX Wheels are quickly becoming the go-to choice for car enthusiasts around the globe.

Please refer to the wheel & tire fitment guide or give us a call before placing an order if you're unsure of fitment.

APEX forging process explained

10K TONS OF PRESSURE

These wheels start as a cylinder of extruded aluminum that is forged by a die under 10,000 tons of pressure. This extreme pressure increases the strength of the material by eliminating porosity and improving the grain structure within the aluminum. It creates the perfect blank canvas to start from for our ultimate wheels.

APEX forging process explained

TO DIE FOR

The designs and sizes offered by many companies are constrained by the blanks they can source from suppliers. What we found didnu2019t meet all our needs so we also designed and developed our own dies to stamp blanks that meet our exact specifications. The result? Our wheels can be made in the key sizes needed for racing.

MORE STRENGTH

u201cForgedu201d doesnu2019t mean strong. Many forged wheels focus on weight reduction so much that they end up with the same load rating as cast wheels. Think all forged wheels are stronger than cast or flow formed? Think again! We added up to 1,000 pounds of extra load capacity per vehicle compared to our flow formed line.

PREMIUM FINISHES

Our forged wheel line enabled us to release the finishes weu2019ve always hoped for. Fully polished aluminum, hand-brushed with tinted clear, and a much wider range of painted finishes. Our forged wheels not only deliver performance but also distinctive new styles as well.

IMPROVED BRAKE CLEARANCE

The flow formed ARC-8 was our first design so it features our older barrel profile with compromised clearance. Typical blank forgings can have even worse clearance than our original wheel. By developing our own new profiles and new dies, they can clear Brembo 380mm kits behind our 18u201d wheels and 400mm carbon ceramics behind our 19u2019s.

WEIGHT OPTIMIZED

We conducted extensive Finite Element Analysis to reinforce high-stress areas and to remove material where it didnu2019t improve strength. The end result is a fully forged wheel with an ideal balance of strength and weight.

PAINTLESS KNURLED BEADS

Not all knurling is created equal. To reduce unwanted tire spin as much as we could, we protected our knurling from paint to keep them sharp. We didnu2019t take the cheaper shortcut of painting over the bead area, which makes the knurling smoother and rounder. See and feel the difference.

TAILORED FIT, OFF-THE-SHELF

APEX is known for stocking many niche and spacer free fitments tailored specifically to a chassis. Weu2019re releasing those same fitmentsu2026 and more in our new forged line. Much lower production requirements will allow us to release a wider range of fitments that were previously off-limits.

TRUE VIA

Many companies promote their wheels as being certified by the VIA when they actually arenu2019t. Thatu2019s like using the USDA logo on food without permission. APEX wheels get officially tested and registered by the VIA in Japan, and we have the proof to back it up.

JWL AND BEYOND

Japanu2019s JWL is a standard for wheel load ratings. Our new forged wheels exceed those ratings by almost 20%. Most manufacturers only meet the minimum, while some even fall belowu2014yet they still claim to be JWL. Always verify load ratings before you buy.
