SM-10 Design
APEX 19 Inch SM-10 BMW Track Wheel Optimized Car Setup
Fit Matters

The right solution for every application

The SM-10 wheel includes details specifically implemented to enhance the BMW 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 for various BMW chassis’s and will work in either square or staggered configurations.

APEX 19 Inch SM-10 BMW Track Wheel Face Profile
Face Profile

One design, many levels of beauty

Two face profiles will be utilized to maximize spoke concavity and reduce weight on the SM-10 design.

The medium concavity is offered on narrow-width applications, while the deep concavity is offered on our wide-width applications. Concavity is dependent on fitment, and not selected independently.

APEX 19 Inch SM-10 BMW Track Wheel I Beam Spokes
"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 size of our SM-10 designs, the I-beam spokes are carefully evaluated from structural aspects to ensure minimal weight, brake clearance, and remarkable strength.

APEX 19 Inch SM-10 BMW Track Wheel Beefire Lip
Beefier Lip

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.

APEX 19 Inch SM-10 BMW Track Wheel Knurled Bead
Knurled Bead

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.

APEX 19 Inch SM-10 BMW Track Wheel Open Center Design
Open Center

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.

APEX 19 Inch SM-10 BMW Track Wheel Hub Centric Design
Hub Centric

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 BMW application. All 5x120mm bolt pattern wheels feature a direct-fit, 72.56mm center bore.

APEX 19 Inch SM-10 BMW Track Wheels clear big brake kits
Brake Clearance

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.

Wheel Hardware

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.

APEX 19 Inch SM-10 BMW Track Wheel Center Cap Design
Center Cap

A factory fit and finish

We don't reuse one cap design for all of our wheels. Every SM-10 wheel is designed to work with factory center caps. You can easily replace APEX center caps with OEM roundels for a clean factory look. The SM-10 wheels will ship with our Gloss Black center cap that mimics the size and shape of a BMW factory center cap.

APEX 19 Inch SM-10 BMW Track Wheels work with OEM and aftermarket TPMS sensors
TPMS

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.

The APEX Standard
APEX 19 Inch SM-10 BMW Track Wheel flow forming technology
Flow Forming

Benefits of forging, without the pain

All APEX wheels, including the SM-10, are produced using the Flow-Forming technique. 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 of the Flow-Forming process is a lightweight and extremely strong barrel that equals that of a traditional forged wheel at a fraction of the cost.

APEX 19 Inch SM-10 BMW Track Wheel is VIA certified
Testing & Certifications

We break a lot of wheels

Computer simulated stress tests are no match for real world testing when designing a lightweight wheel that will see extreme loads. All APEX wheels are crush and load tested to exceed JWL standards and those results are independently tested and certified in Japan by the 3rd party agency known as the VIA. Countless wheel companies falsely claim they are tested and certified by the VIA, and so they lack the certificates to prove it. We test and certify each and every design, diameter, width, and offset, separately.

Weight & Strength Optimization

It's all in the details

We’re taking more time than ever before on this step, revising and iterating our design to reduce weight as much as possible. We’re on this step right now and we’re still shaving off a fraction of a pound at a time. After many months of BMW-specific optimizations, we’ve minimized weight while maximizing strength. 19” wheels typically have less tire protecting them from the imperfections in the road, 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.

APEX 19 Inch SM-10 BMW Track Wheel Available Finishes
Finishes

Because being faster is just not enough

The SM-10 wheels are 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 wheels leaves lug holes, center bores and mounting pads untouched, which ensures proper fit and torque values.

APEX 19 Inch SM-10 BMW Track Wheel Warranty
Warranty

A wheel you can depend on

All APEX wheels are backed by a 2 year structural warranty and a 1 year finish warranty to the original. This warranty guarantees that all APEX wheels will be free from defects in materials, workmanship, and paint finish under normal and reasonable use.
