APEX Wheels | Introducing Our Forged Sprint™ Line - Our Lightest Wheels



Our forged Sprint™ line was built to be extremely light while still offering a meaningful strength increase over our flow formed wheels.

➡︎ 10K ton forged 6061-T6 aluminum

➡︎ Stronger Sprint™ spec inner lip

➡︎ Side-milled spokes for reduced weight

➡︎ Massive brake clearance

➡︎ Independently tested and certified

Specifications and ETAs for our Sprint™ Line designs

10K Tons Of Pressure



Our new forgings weigh as much as 120 pounds before machining. To form such a thick blank we require special equipment capable of 10,000 metric tons of pressure. This extreme pressure increases the strength of the aluminum by eliminating porosity and improving the grain structure.

True Motorsport Blanks


Many companies use 3rd-party blanks intended for non-motorsport wheels which can severely limit sizes, concavity, spoke design, and critical brake clearance. We designed our very own blank profiles from scratch which gives us total control over the final product, resulting in exceptionally deep spokes and stronger designs.
Learn more about our true motorsport blanks.



Side-milled Spokes



One of the most significant upgrades to our Sprint wheels is the addition of wider and deeper side-milled spokes. Any excess material that doesn’t add strength is carved out using a precision CNC ball cutter. Side-milling is often deemed cost-prohibitive by others, but for true performance without compromise we believe it's essential.

➡︎ 40-50% Wider
➡︎ 50-100% Deeper

Learn more about our wider and deeper side-milling.


A Stronger Lightweight Wheel



Our forged Sprint™ wheels are lightweight without the strength compromises found on typical lightweight wheels. First, we carved out as much material as possible, then we purposefully added one pound back to reinforce critical areas, creating a stronger inner lip and a higher load rating.¹ What’s the point of a lightweight wheel if it’s fragile?


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.


Independently Tested


We don't rely solely on computer simulations or unverifiable in-house testing. We believe independent testing is critical to protect consumers in this unregulated industry. We chose STL, an independent lab in Ohio, to test our Sprint™ wheels far above JWL standards, including increases in testing duration, impact drop height, and total load.
Learn more about our rigorous independent testing.


Tough Inner Lip


Introducing the Sprint™ spec inner lip, with a unique channel profile that makes it even stronger than our previous designs. So even though our Sprint™ wheels are pounds lighter than comparable flow formed wheels, the inner lip is stronger.

➡︎ 32% more reinforcement than our flow formed wheels.

Learn more about our Sprint™ spec inner lip.


Big Brake Clearance


From day one, APEX has been on a mission to build wheels that clear big brakes. Our new forged wheels are the product of everything we’ve developed over the past 10+ years, including an innovative high-clearance barrel design and vehicle-specific spoke profiles.


Deeper Concavity


Our new forgings were redesigned to create extra deep, concave spoke profiles. Their new shape allows us to make any profile, from flat to deep and everything in between. Each one is optimized for a specific application using 3D laser scans of factory and aftermarket brake kits.


Paintless Knurled Beads


Whether it's a day at the track or months of street driving, repeated hard braking and acceleration can make a tire slip along the bead seat and go out of balance, causing vibration. Knurled beads help, but are less effective when painted over. Our forged line features unpainted knurled beads that stay sharp and maximize grip.
Learn more about why our forged wheels have unpainted knurled beads.


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.




Laser-Engraved Specs


As track enthusiasts ourselves, we know how frustrating it is to try to locate and decipher wheel specs that have been hastily hammered into the rim or become unreadable over time. With our new Sprint™ wheels, we chose to invest a little extra and laser-engrave the specs on the barrel, in plain sight, making them easy to find and read. (You’re welcome.)

How APEX Engineers A Better Track Wheel

Crazy to think, but this is our first ever, in-depth video about any of our wheels.

Our engineering team put 2 years of hard work into our new Sprint Line and the forging dies that made them possible, so we were compelled to create a technical video that dives into the details. This video has a lot of great content our product descriptions don’t include. After watching, we’re confident you’ll truly appreciate why these features are so valuable.

If you're craving more content, this should quench your thirst.

We've added the full tables of incoming fitments and their specifications/ETAs to the OP. As you can see, this is a massive range of wheels that we will be bringing to market over a short time frame and this is only the beginning! Fitments that are not a part of the current ongoing Group Buy will have their own associated Group Buys prior to their arrival.

As a group of track enthusiasts and racers, we understand how frustrating it can be to bend a wheel in pursuit of a PB or podium finish. Whether you find yourself 4 wheels off track on a safari excursion or creating your own driving line jumping treacherous berms, wheels are put through a tremendous amount of stress and abuse in the process – sometimes simply being forged isn’t enough to avoid bends.

To mitigate this, our engineers made a concerted effort to reinforce the inner lip of these motorsport wheels and created our stronger, Sprint™ Spec inner lip design. If you haven’t already, we recommend you read our technical writeup on our Sprint™ Spec inner lip.

When Function Meets Form



As wheel specialists, we understand that when it comes to reducing weight and increasing stiffness in wheel spokes, there is a big difference between functional and aesthetic side milling. Instead of milling a few negligible millimeters of depth just to look cool, our engineers optimized our new motorsport blanks to create narrower yet significantly deeper spokes with deeper side milling that is nearly 50mm wide on some wheels. The result is a stiffer “I” beam-spoke shape that also showcases a stunning aesthetic. If you haven't already, we recommend you read our technical write-up on our deeper and wider side-milling.

With the release of our new forged Sprint Line wheels, we’ve had a few customers asking about how our upcoming EC-7RS visually compares to the classic forged EC-7R.


The overall design is obviously similar as this is our third iteration of the EC-7 design itself. Between the Classic Forged EC-7R and the new Sprint Line EC-7RS, the biggest visual difference will be seen in the spoke depth and side milling. Our new Sprint™ line of wheels features much deeper and wider side milling on the spokes versus our first generation of forged wheels. This improvement was made possible by our new motorsports blanks which allow us to create narrower yet significantly deeper spokes. The larger surface area on the side of each spoke allows us to take more material out. Doing so creates a much stiffer “I” beam or c-channel spoke shape. Visually that means the EC-7RS has deeper but thinner spokes with deeper side channels. The spokes of the EC-7RS also connect to the outer lip of the wheel, unlike our older EC-7R. This further reinforces the outer lip.



The inner lip won’t be easily seen when the wheels are mounted but has been updated with a unique C-channel as a result of a full redesign for additional strength in this crucial area. The inner barrel now includes laser etching to make specification identification a breeze and is a completely redesigned profile for even better brake clearance.


Porsche-spec etching shown

Ultimately, these changes were driven by our goal of improving our product offerings in a meaningful way. Beyond expanding the width and diameter offerings to fitments we’ve never before produced, these fundamental changes have resulted in higher performance wheels with an aesthetic that we are extremely excited about. 5x120 EC-7RS BMW fitments will be incoming with Group Buys of their own in the next few months. Stay tuned!

Get To Know Our 50% Replacement Program


Let’s face it: Whether you are a weekend warrior practicing at the track, or a club racer pushing the limit for a podium finish, mistakes happen, and parts can get damaged along the way. We are not really a performance company if we sell wheels in a way that penalizes the pursuit of driving at the limit. For this reason, we stepped up and created a program to significantly reduce the costs of properly maintaining a set of wheels by making replacements extremely affordable.

Our goal was to make replacing a damaged wheel with a brand-new one much more appealing than ignoring the problem or performing any questionable and compromising repairs. This program will also help keep damaged wheels from being passed on to unsuspecting enthusiasts via the secondhand market.

Discounted replacements are ideal for customers who accidentally damage their wheels with curb rash, bends or dings from potholes, berms, road debris, and off-track excursions. Complete destruction of a wheel from serious accidents also qualify, including tire wall or barrier impacts, contact with other racers, or any accidents resulting in a total loss.

All pledged members that participate in this Group Buy would be eligible for this replacement program. For more details, be sure to visit our website here.

VS-5RS Profile Comparison


With so many new fitments available in our all new VS-5RS design, we’ve gotten a few requests to showcase the various profiles available. While all of our Sprint™ Line designs have their profile optimized on a per-application basis, we’ve categorized these wheels into 4 Profiles based on their depth for easy identification. Our investment in the Motorsport Blanks mentioned in the post above has allowed us to make Profile 4 wheels for the first time via additional material available to our engineers during the design phase of this project. These are the most concave wheels we’ve ever made and they help round out the Sprint™ Line which stretches from narrower high offset fitments for Porsche and non-M BMW chassis to wider low offset wheels for Domestic and widebody applications.

It may not be a Z4, but we thought we’d share some photos and a video of this 1M on our new VS-5RS wheels. With a set of square 18x10 ET25 wheels and suspension architecture and other parts plucked straight from the E9X M3, we can’t imagine a better way to tear up the canyons.









Full Feature Thread


Technical article

All APEX Sprint Line forged wheels feature unpainted knurled beads. The problem with knurling is that it varies by manufacturer in design and effectiveness. Whether it’s a day at the track or months of street driving, repeated hard braking can make a tire slip on the bead seat and go out of balance, causing vibration.

Maintaining the effectiveness of our knurling was at the forefront of our minds when developing our new line of forged wheels, which is why there’s no paint covering the bead area. Instead of adding basic knurling with paint over it just to check that feature box from a marketing perspective, our engineers optimized the functionality of our knurled beads by leaving them unpainted to ensure they have a more effective “tooth” to bite into a tire’s bead. It is a more expensive process, but it is one of many details that results in a better wheel. To learn more, be sure to read our technical write-up below.
