- SM-10 Design

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 our 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 our 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, 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.

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.

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.

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. 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
