The new SM-10RS, part of our Sprint™ Line of forged wheels, features reduced weight and greater stiffness to improve lap times.
As part of our Forged Sprint™ Line, the SM-10RS was built to be extremely light while still offering a meaningful strength increase over our flow formed wheels. For those looking to shed as much weight as possible to improve lap times.
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.
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 to give us total control over the final product.
One of the most noticeable features of the SM-10RS is its use of side-milling on both sides of each spoke, creating an I-beam effect. 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.
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?
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
The SM-10RS is not just another style to choose from. We used Finite Element Analysis of bending loads to optimize spoke geometry for greater stiffness without increasing weight. In fact, the SM-10RS is nearly identical in weight to our popular VS-5RS yet almost 10% stiffer, and 25% stiffer than our first generation of forged wheels.
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.
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.

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.
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.
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.
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.

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.)
All SM-10RS wheels are purpose built for select vehicle applications. Very few applications require centering rings.
The majority of SM-10RS wheels come with a gloss black APEX cap which is interchangeable with your OE center cap*. Select JDM applications feature a capless center section. See vehicle product page for more details.
* Capless-center and centerlock wheels do not include APEX center caps. Certain unique fitments support an APEX center cap that is not interchangeable with the OE cap. See your vehicle-specific product page for additional details.
Wherever possible, APEX wheels are designed to be used with OEM mounting hardware* as well as high-quality wheel spacers, stud conversion kits, wheel locks, and more. See our Accessories pages.
*A small number of applications use conical mounting hardware in place of the OEM ball seat hardware. Visit individual product pages to confirm hardware type/compatibility.
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.
All APEX wheels come with a
lifetime structural warranty against defects in
workmanship and materials, plus a 1 year finish warranty.
Exchanges are fast, easy, and hassle-free.

We’ve tirelessly test-fitted hundreds of setup combinations in order to provide direct-fit, spacer-free wheel packages for everything from showroom-fresh cars to all-out race builds. Our detailed fitment guides help you avoid costly trial-and-error and walk you through every step of finding your perfect setup.
We race in NASA Super Touring ST4 and several WERC endurance races throughout the season. In order to continue reaching the podium, we can’t be second guessing the strength of our wheels. We chose the forged EC-7R wheels to handle everything we throw at them and haven’t looked back.
As a club racing team owner, I chose APEX wheels for their style, weight, performance and durability for the price. We’ve won a number of national championship races on these wheels.
APEX has some really good Fitment Guides that help you figure out the perfect fitment for street, track or race. All the research is done for you. Just pick your wheel specs. I couldn't be more happy with the setup on my E92 M3.
Apex has managed to hit the sweet spot for design, function, durability and price. After a full race season of curbs, contact, and a couple field trips... both sets of wheels are perfectly round and true. Based on our PCA racing experience with APEX wheels we bought them for our American Endurance Racing car too - a no brainer.
The last thing a driver needs when he’s tackling curbs and putting in laps is to worry about bending wheels. I prefer APEX wheels to any other brand. Their replacement program is the best in the business and offers racers like me peace of mind, so I can focus on driving fast.
