APEX SM-10 | 19" x 9" ET30 | 5x120mm | 72.56mm

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 tyre 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.

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 wide-width applications. Concavity is dependent on fitment, and not selected independently.

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 the SM-10 designs, the I-beam spokes are carefully evaluated from structural aspects to ensure minimal weight, brake clearance, and remarkable strength.

By saving weight elsewhere, APEX have added extra material where it counts. They've beefed up the barrel’s inner lip on the SM-10 to better handle the repetitive abuse seen on the track.

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 centre 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.

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 centre bore.

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. APEX have 2D modelled 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.

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 don't reuse one cap design for all of their wheels. Every APEX wheel is designed to work with factory centre caps. You can easily replace APEX centre caps with OEM roundels for a clean factory look. APEX wheels will come with the redesigned, Gloss Black centre cap that mimics the size and shape of a BMW factory centre cap.

TPMS sensors, which monitor tyre 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 centre caps. All APEX wheels accept OEM and aftermarket equivalent TPMS sensors, and any standard sized metal or rubber valve stem.

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 aluminium 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.

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 they have the proof to back it up.

Japan’s JWL is a commonly followed standard for wheel load ratings. The APEX 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.

APEX took more time than ever before on this step, revising and iterating their design to reduce weight as much as possible. After many months of BMW-specific optimizations, APEX minimized weight while maximizing strength. 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.

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.

As of recent, all APEX wheels now come with a lifetime structural warranty and 1 year finish warranty, so you can be confident in your purchase. Please contact us for the full terms and conditions.
