APEX SM-10 Race Wheel 18x9.5 ET35
It's no coincidence that you'll see this fitment on most E46 M3s at the track. It's a rotatable square fitment that supports 265 or 275 tires with zero or minimal modifications. May require spacers, but has a very street-friendly front camber requirement. Huge variety of tire brands and compounds available.
Classic flow-formed race wheels a modern motorsport design crafted using advanced weight saving techniques with a reinforced inner lip and I-beam spokes.

Recommended Tire Options
Any Ultra High Performance, Max Performance, or Extreme Performance summer tires will work great with these fitments, depending on your personal ratio of street to track driving. Other tire sizes may also work in addition to what’s listed below.
Nitto NT01 (100TW) - The NT01 is one of the highest performing track day tires on the market and is available in all of the most popular sizes. This tire is not recommended for a daily driven car, or even for a car that is driven to and from the track. These tires will wear extremely quickly and are best used for cars that are trailered to and from events.
Hankook Ventus R-S4 (200TW) - For drivers who are looking for a dual duty tire that can hold its own on the street and on track. While this is not the fastest track day tire available, it is long lasting, and tire noise is kept to a minimum for those long drives to and from the track. These tires are more than capable of setting impressive times on track, despite their great manners on the street.
Bridgestone Potenza RE-71R (200TW) - For drivers who are looking for a tire that can be used sparingly on the street, while still being capable of keeping pace with all other R compound tires on the track. The RE71R is one of the fastest tires available for track use, with the main downside being that these tires are made of a very soft compound that can wear quite quickly. This is an excellent tire for a track focused street car, that spends a majority of the time on track.
Nitto NT05 (200TW) - For drivers who are willing to sacrifice wet weather performance for a high level of dry weather traction. Can be daily driven but really only recommended for occasional drives on the street, and for track days where the driver can take advantage of all grip available.
Michelin Pilot Sport 4S (300TW) - For drivers who are looking for class leading performance on the street while still maintaining grip and longevity for occasional track days. This is the perfect tire choice for the enthusiast who does a majority of their driving on the road, while attending 2-3 driving events per year.
Fitment Type: Performance Street/Track
Recommended for: E46 M3. These “dual-duty” fitments are recommended for enthusiasts focused on maximizing performance, whether you use your car primarily on the street, or you’re a weekend warrior attending autoX and/or track days. This category includes both staggered and square configurations to best suit each individual drivers priorities, goals and preferences for their vehicle. While many of these fitments can be achieved without any modifications, there are variables at play like vehicle ride height, suspension type, and tire size/brand which may require additional work to prevent rubbing.
Drivers going this route should be open to modifications like dialing in negative camber and/or lightly rolling the rear fenders to prevent/minimize rubbing. Even if your wheel and tire configuration does not require negative camber to fit under the fender arches, we highly suggest dialing in negative camber to maximize grip throughout the corners, and to improve turn-in. Negative camber will also ensure you are leveraging your extreme summer or R-compound tires to their fullest potential, and will dramatically extend the life of your tires.

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.
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 the APEX 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 has added extra material where it counts. The barrel’s inner lip is beefed up on the SM-10 to better handle the repetitive abuse seen on the track.
OPEN HUB 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.
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.
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.
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.
CENTER CAP
A factory fit and finish
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 the redesigned, Gloss Black center cap that mimics the size and shape of a BMW factory center cap.
TPMS SENSORS
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.
