18x10" ET40 APEX SM-10 Mustang Wheel

Fit Matters

The right solution for every application

The SM-10 wheel includes details specifically implemented to enhance the Mustang 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 exclusively for S197 and S550 chassis and will work in either square or staggered configurations. GT350s applications require 19" wheels.

Face Profile

One design, many levels of beauty

The SM-10 wheel was created in three increasingly-concave face profiles; The shallowest face provides maximum caliper clearance on narrow applications, while the deepest concave face reduces weight and creates a stunningly aggressive appearance on wide-width applications. All Mustang SM-10 wheels are built with a profile 2 - medium concavity face profile, as that yields optimum results with each of the wheel specifications.

"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 concavity profile of our SM-10 design, 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 Mustang S197 or S550 application. All 5x114.3mm bolt pattern wheels feature a direct-fit, 70.5mm 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. Good news GT350 owners, these wheels not only clear your massive Brembo brakes, the barrel to caliper clearance is quite impressive.

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.

TPMS

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.

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 our wheels now come with a lifetime structural warranty and 1 year finish warranty, so you can be confident in your purchase. Terms and conditions sent to buyer per request.
