Introducing the all new Apex Forged Enduro Line wheels. Designed to withstand the combined stresses of extra sticky tires, crazy downforce, fast drivers, and inevitable mistakes. Part of our commitment to Real Performance, these are our strongest and most durable wheels, with dramatically higher load ratings, stiffer spokes, and tougher lips.
There’s a constant industry push for lighter wheels, but if saving weight is the top priority then strength and stiffness can be compromised. We see it compromised often in the pursuit of lower advertised weights, and many cars end up ill-equipped as a result. The reality is that all enthusiasts could benefit from stronger and stiffer wheels, while some critically require it.
The Enduro Line wheels are significantly stronger and stiffer compared to a Sprint Line model with the same spoke configuration, and even more so than many competitors. Adding the Enduro Line to our Forged wheel catalog gives drivers the option to choose what’s best for their needs. The intention is for the Enduro Line to become the new de-facto wheel of choice for track day enthusiasts and racers alike.
Faster drivers put much more stress on wheels than novice and intermediate drivers do. That stress is magnified by extra sticky tires and higher cornering G’s. If you add a lot of down force to a car with a wing and splitter, then that force will directly translate to an increased load on the wheels, just as if the car weighed much more. If the car is already heavy to start with, the loads can get high real quick.
Combine all those stresses together and you absolutely need a wheel with a higher load rating. Just like how heavier vehicles and trucks need progressively higher load-rated tires as the weight goes up, motorsport applications with higher wheel loads need progressively higher load ratings just to keep up.
So, why should most enthusiasts first consider our stronger Enduro wheels as opposed to a lighter alternative? Think about it for a moment. How much faster will an intermediate level driver’s HPDE lap be with a slightly lighter wheel vs. how much expensive damage can they avoid by running stronger wheels? Off track incidents are an inevitable part of the learning process. How many positions or wins does a racer give up if they experience damage after contact or an off-track excursion mid race? How much time do they give up from spokes that flex so much under load that their alignment significantly changes?
The Enduro line trades a little extra weight for a lot more strength, which is most often the better choice for enthusiasts in the long run.

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.
Side-milled spokes
One of the most significant upgrades to the EC-7RS 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.
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.² 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.
Tougher 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.
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.
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.
