A FITMENT FOR YOU
Need help selecting the proper wheel fitment for your BMW? APEX Race Parts have 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.
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 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.
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 wide-width applications. Concavity is dependent on fitment, and not selected independently.
"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 the SM-10 designs, the I-beam spokes are carefully evaluated from structural aspects to ensure minimal weight, brake clearance, and remarkable strength.
Beefier Lip Ready for more abuse
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.
Open Hub Centre 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 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.
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 centre bore.
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. 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.
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.
Centre Cap A factory fit and finish
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 They all fit
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.
THE APEX STANDARD
Flow Forming 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 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.
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 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.
Weight & Strength Optimization It’s all in the details
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.
Finishes 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.
Lifetime Warranty A wheel you can depend on
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.

Good keyboard, some auxiliary keys are moved from where I was used to
I've only been using this for a day, so I can't speak about battery life. It is rechargeable, and it has an on-off switch for saving the battery when I'm not using it, so I don't know what more I could ask for on that front. Likes: the main keyboard is definitely ergonomic and feels comfortable; the key action is not silent, which I actually like, and the scissor action switches underneath the keys feels good to me; the keyboard is about 1.5" narrower than my previous keyboard (Logitech Ergo K860) because the number pad is right next to the regular part of the keyboard, and the usual keys in between have been rearranged. Most of these changes will just require the user to get used to the new positions. However, the Home, End, Pgup and Pgdn keys are now Function keys, piggybacking on the arrow keys, and that may cause more trouble for people who use those a lot (I don't, so I don't mind it). Dislikes: experience has shown me that dust and crud get into the space between the wrist pad and the rest of the keyboard. On my old keyboard, I could remove the wrist pad using some tiny screws in the back, and take the pad out for thorough cleaning. With this keyboard I won't be able to do that, so time will tell how aggravating that will be. Maybe I'll have to take it down to my shop and blow out the crud with the air compressor (joking, probably not a good idea). Overall, not quite 5 stars, but close. If it lasts better than the Logitech, I may come back and put in that last star.
Update: It has lasted about 20 months, and I'm going to have to replace it. I may buy another one, 20 months is pretty good for the amount of use I have gotten out of it, but I'm going to search to see if anything new and better is around. Symptoms seem to indicate that the rechargeable battery is not taking a charge any more. The keyboard works find when it is plugged in, but when I unplug it, after a few minutes it goes wacky.

Arrived Battery DOA - But then something unexpected happened.
This was a one star review because the unit arrived with a batter that would not hold charge for more than a minute. I am not changing the stars, because if you are like me, you read the one star reviews cause so many companies pay for fake 4 and 5 star reviews.
When I first posted this review I also initiated a return and just planned to move on to another brand. I was surprised when I got a personal email from the Arctek Service Team offering to send me a replacement free of charge. With nothing to lose I figured why not?
The new unit arrived and I put a full charge on it and put it to work. I chose this keyboard because it is the closest in layout to the original Microsoft ergo split keyboard, no longer in production, that I have used for years and truly enjoy. I am pleased to report that the battery is working fine and the keyboard performs flawlessly. No skipped strokes or stuck keys, no glitches with the proprietary wireless interface to the laptop (when I am using it on the desk with a large screen).
My hat is off to the Arctek service team and management. A company that cares enough about its reputation and customers to go to so much effort to take care of a customer with such a small dollar item sale is a company you can expect to rely on. From now on when I want electronic gear on Amazon, I am going to use the word Arctek in my search.

Incredible
1 year update: I have been using this keyboard daily at work for almost one year and my 5 star review stands. Upon receiving the keyboard I charged it before use, and since then I have not charged it at all and it is still somehow at 75% battery!! I turn it off at night when I’m done.
One of the function keys broke off in a way where I can’t reattach it, but I reached out to customer support and they sent me a free replacement keyboard. Great customer service and warranty!
Original review: I love this keyboard. I am a grant writer so I write and edit all day. It has really leveled up my typing experience and has made work much more comfortable. It puts my hands in a natural position so my wrists no longer bend at odd angles. I adapted to the split key design in minutes. The keys have an excellent feel and sound to them and the wrist pad feels like a soft cloud. I’ve had no connectivity issues and so far the battery has been stellar. It also has rubber grippers on the bottom so it stays firmly in place on my desk and doesn’t move around like my old keyboard did. I went for this one because I didn’t want to spend $100+ on a keyboard and I’m really impressed with the quality.

OK, but .....
It is an ok keyboard with an annoying flaw. As other reviewers have observed, the placement of the Number Lock key makes it easy to trip that key by error. it is distracting to have to break your train of thought to fix the problem.

Great value for quality design
Super sturdy and sleek. It is exactly what I needed. It is small enough to move around when I move my laptop. I use it on a slide out from my desk so that I can work while I watch TV. It also keeps my laptop cool with airflow on all sides. It couldn't be simpler.
