The right solution for every application
These concave SM-10 wheels are designed specifically for your Porsche. The SM-10 provides chassis optimized fitments and proper load distribution. If you’re looking for a cost effective lightweight 18” wheel, this is your answer.
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.
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.
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.
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.
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.
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.
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.
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
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.
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 we have the proof to back it up. Learn more about false VIA claims.
Japan’s JWL is a commonly followed standard for wheel load ratings. Our 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. Learn more about wheels that aren’t JWL.
Weight & Strength Optimization
It’s all in the details
We didn’t just redrill and recycle our 5×120 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.
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.
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.
50% Off Replacement Wheels
Hit those berms like you don’t care
Do some serious damage to a wheel that’s not covered under warranty? No worries. Curb rash or even totally mangling a wheel in a car accident is covered by our APEX360° program. We offer replacements for wrecked wheels at 50% off our standard prices. See our full terms and conditions for more details.
