Back by popular demand, we are happy to announce our mid-season community Group Buy. Our 19” SM-10 Mustang wheels are available in both staggered and rotatable square fitments, providing S197 and S550 enthusiasts alike with lightweight, flow formed solutions to meet their specific needs. Whether you are enjoying your machine on the street or as a weekend track warrior, we’ve got you covered. Go wider, go lighter!..
The Mustang version of our SM-10 wheel design has been optimized specifically for this application and is offered in widths up to 11.5” wide. These aren’t just redrilled BMW wheels. We’ve thickened spokes and FEA optimized every size for a 10% higher load rating above the JWL/VIA standard. As usual we setup the wheel to work with OEM S550 Mustang center caps, mounting hardware, and TPMS.
The SM-10 design is equipped with I-beam spokes to offset as much weight as possible from where we’ve beefed up the wheel. It also features a knurled bead along the barrel that helps keep a truer balance by reducing tire slippage on the rim. The SM-10 wheel design offers massive brake clearance, effectively clearing all known aftermarket big brakes kits as well as popular factory big brakes like the S197 14” and 15” GT500 Brembo kits, S550 Performance Package Brembo kit, and the massive GT350 and GT350R Brembo kits.

A staggered fitment is best suited for enthusiasts looking to maximize rear end grip.
A rotatable square fitment is best suited for track or performance driving enthusiasts looking to maximize the car’s handling potential, while maintaining the ability to rotate wheels and tires efficiently on all four corners. This tremendously mitigates the seasonal tire budget!
¹ Approx. 25mm front spacers required (some aftermarket coilovers may allow you to reduce spacer thickness)
² Will require approx. 25mm spacers and extended wheel studs up front, as well as adjustable camber plates. Some aftermarket coilovers may allow you to reduce spacer thickness.
A non-rotatable square fitment is best suited for track or performance driving enthusiasts looking to maximize the car’s handling potential, however the axle specific offsets ensure that no spacers or extended wheel hardware is required.
* Adjustable camber plates required
The right solution for every application
The SM-10 wheel includes details specifically implemented to enhance the Mustang owners' track day and street performance experience. An optimized car setup begins with the right wheel and tire fitment, and without model-specific attention, maximum performance is compromised. These wheels were developed exclusively for S197 and S550 chassis including the GT350, and will work in either square or staggered configurations.
One design, many levels of beauty
The SM-10 wheel was created in three increasingly-concave face profiles; The shallowest face provides maximum caliper clearance on narrow applications, while the deepest concave face reduces weight and creates a stunningly aggressive appearance on wide-width applications. All Mustang SM-10 wheels are built with a profile 2 - medium concavity face profile, as that yields optimum results with each of the wheel specifications.
"I" Beam Spokes
More than just a pretty face
The spokes of the SM-10 were designed to be robust where they need to be, and extra lightweight where they should be. Weight is reduced by CNC machining material out from the sides of each spoke. It’s expensive and avoided by almost every manufacturer, but affordable with volume. In each concavity profile of our SM-10 design, the I-beam spokes are carefully evaluated from structural aspects to ensure minimal weight, brake clearance, and remarkable strength.
Ready for more abuse
By saving weight elsewhere, we’ve added extra material where it counts. We’re beefing up the barrel’s inner lip on the SM-10 to better handle the repetitive abuse seen on the track.
Keep a true balance
We’ve upgraded these wheels to include a knurled bead seat to reduce unwanted tire rotation. This machined knurling throughout the wheel’s barrel increases friction between the wheel and tire to combat excessive tire slippage and maintain a true balance. Braking deep into a corner, bouncing off berms at the apex, and applying throttle at corner exit all apply enough tire load to cause unwanted tire slippage. Arrive to the track with balanced wheels and tires, leave the track with balanced wheels and tires.
Easy to access lugs
Race wheels can't just be light, they need to function in a high performance environment. Unlike the narrow lug recesses of most other wheels, the SM-10 wheel features a wide open hub center that easily accommodates oversized race lugs and beefy impact sockets. This allows for quick and easy wheel changes and prevents chips and scratches from tools.
No rings or adapters here
All APEX SM-10 wheels are purpose built for select vehicle applications, and centering rings are never required for any Mustang S197 or S550 application. All 5x114.3mm bolt pattern wheels feature a direct-fit, 70.5mm center bore.
A lot of room in a tight space
Spoke clearance is only half the problem. The barrel construction on a wheel also needs to be big enough to clear the sides of your caliper and rotor. Many aftermarket wheels that have aesthetic compromises in their design may work with smaller stock brakes, or smaller diameter big brake kits, but the larger kits will pose a major problem. The barrel of the SM-10 wheel offers unmatched caliper clearance because wheels shouldn’t limit your choice of aftermarket brake kits, and brake kits shouldn’t force you to run oversized wheels. We 2D modeled most Big Brake Kits available in Solidworks and tweaked the wheel design of the SM-10 prior to production in order to fit as many kits as possible. Good news GT350 owners, these wheels not only clear your massive Brembo brakes, the barrel to caliper clearance is quite impressive.
Original or Aftermarket, it all works
The SM-10 wheel can be used with all OEM and aftermarket mounting hardware with a 60° tapered seat. Lug bolts, wheel locks, and stud conversion kits all work perfectly. The SM-10 wheel also accepts wheel spacers without issue. The shallow rear chamfer allows the wheel to remain hub centric even when 5mm flat spacers are used. The chamfer is deep enough to clear the chamfered lip found on some aftermarket spacers that would typically cause improper seating of the wheel and, therefore, wheel vibration.
They all fit
TPMS sensors, which monitor tire pressure, are one piece of technology that can't be compromised. The attention to OEM compatibility on the SM-10 wheel doesn't end with center caps. All APEX wheels accept OEM and aftermarket equivalent TPMS sensors, and any standard sized metal or rubber valve stem.
Benefits of forging, without the pain
These APEX wheels are produced using a manufacturing process known as flow forming. This process significantly reduces weight in the barrel, which has the greatest impact on rotational mass. During the manufacturing process, rollers apply high pressure to the inner barrel, compressing the aluminum into its final shape. This effectively eliminates porosity and aligns the grain structure of the metal, which increases tensile strength. The end result is a lightweight and extremely strong barrel that equals that of a traditional forged wheel at a fraction of the cost.
Testing & Certifications
Verifiable 3rd party testing
Many companies promote their wheels as being certified by the VIA when they actually aren’t. That’s 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. Learn more about false VIA claims.
Japan’s JWL is a commonly followed standard for wheel load ratings. Our flow formed wheels meet, and most exceed, their load rating requirements. Most manufacturers only meet the minimum while some don’t even do that. Check and verify load ratings before you buy. Learn more about wheels that aren’t JWL.
Weight & Strength Optimization
It's all in the details
We didn’t just redrill and recycle an old wheel. We’ve rebirthed it specifically for Mustang use. After many months of Mustang-specific optimizations, we’ve minimized weight while maximizing strength. Heavy cars need beefy wheels, and that calls for load ratings that are 10% above the JWL/VIA’s standard. The result is a lightweight wheel with extra strength in all the right places. Use the SM-10 with confidence on both street and track.
Because being faster is just not enough
The SM-10 wheel is available in multiple finishes. All APEX wheels are finished using a comprehensive multi-stage liquid paint system over a powder coated base coat. Standard finishes include gloss-metallic finishes, and semi-gloss or matte finishes. Often overlooked, painted or powder coated lug hole seats can cause hardware to loosen or begin the spread of paint chipping to more visible sections. The coating process of the SM-10 leaves lug holes, center bores and mounting pads untouched, which ensures proper fit and torque values.
