The FL-5 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.

Two lip depths will be utilized to maximize spoke concavity and reduce weight on the FL-5 design.

The medium lip is offered on narrow-width applications, while the deep lip is offered on our wide-width applications. Lip depth is dependent on fitment, and not selected independently.
The spokes of the FL-5 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 FL-5 designs, the I-beam spokes are carefully evaluated from structural aspects to ensure minimal weight, brake clearance, and remarkable strength.
We use rotary forging for both the front and rear barrels on our FL-5 wheel designs. This produces the strongest lips possible, and we can optimize the depth of the front lip for every unique width and offset.
By saving weight elsewhere, we’ve added extra material where it counts. We’re beefing up the barrel’s inner lip on the FL-5 to better handle the repetitive abuse seen on the track.
All APEX FL-5 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.
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 FL-5 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.
The FL-5 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 FL-5 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.
We don't reuse one cap design for all our wheels. Every APEX wheel is designed to work with factory center caps. You can easily replace APEX center caps with OEM roundels for a clean factory look. APEX wheels will come with our redesigned, Gloss Black center cap that mimics the size and shape of a BMW factory center cap.
TPMS sensors, which monitor tire pressure, are one piece of technology that can't be compromised. The attention to OEM compatibility on the FL-5 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.
All APEX wheels 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.
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.
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.
The SM-10 and FL-5 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 wheels leaves lug holes, center bores and mounting pads untouched, which ensures proper fit and torque values.
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.
