SM-10 DESIGN

Fit Matters

The right solution for every application

These concave SM-10 wheels are designed specifically for your Porsche. The SM-10 provides proper load distribution and chassis-optimized fitments that allow enthusiasts to run their desired tire size and compound without sacrifice. If you’re looking for a cost-effective lightweight 18” wheel, this is your answer.

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.

"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.

Knurled Bead

Keep a true balance

We’ve upgraded these wheels to include a knurled bead seat to reduce unwanted tire rotation. This added feature will help keep your balance stay more true throughout the life of the tire.

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.

Brake Clearance - Barrel

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. Targeted at the serious performance-minded owner, 18” SM-10 wheels clear up to 380mm rotor, 6-piston brake kits including the factory PCCB’s.

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 wheels are purpose-built for select vehicle applications, and centering rings are never required for any Porsche application. All 5x130mm bolt pattern wheels feature a direct-fit, 71.6mm center bore.

Center Cap

A factory fit and finish

We don't reuse one cap design for all of our wheels. Every SM-10 wheel is designed to work with factory center caps. You can easily replace APEX center caps with OEM Porsche crest caps for a clean factory look. The SM-10 wheels will ship with our Gloss Black center cap that mimics the size and shape of a Porsche factory center cap.

Wheel Hardware

Original or Aftermarket, it all works

The SM-10 Porsche wheel can be used with all OEM and aftermarket mounting hardware with a ball seat lug recess. 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 Sensors

They all fit

TPMS sensors, which monitor tire pressure, are one piece of technology that can't be compromised. All APEX wheels accept OEM and aftermarket equivalent Porsche/HUF TPMS sensors, and any standard sized metal or rubber valve stem. Use the chart below to help select the correct TPMS for your vehicle.

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 aluminum 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.

Weight & Strength Optimization

It’s all in the details

We didn’t just redrill and recycle our 5x120 SM-10 design, we’ve rebirthed it. After seven months of Porsche-specific optimizations, we’ve minimized weight while maximizing strength. Strength tested to JWL/VIA standards. Since most Porsches have an inherent rear weight bias and run wide rear wheels, we’ve strengthened the inner lips. 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, 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. See here for full terms and conditions.
