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.

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 .

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.

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.

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 .

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

We’ve done countless hours of test-fitting to come up with the perfect chassis-specific widths and offsets. Whether you’re looking for a clean and conservative OEM+ fitment or an all-out aggressive track/race setup, we’ve got you covered. Check out our fitment guides below.

The new decade has arrived, which means there is no better new years resolution than to prepare for the upcoming season. We developed our 18” SM-10 Porsche wheel line to meet the diverse needs of the Porsche performance driving community. The SM-10 wheel design offers new and exciting aesthetic and functional features that build on existing APEX principles: Strong, Lightweight, Affordable. Weight is reduced by CNC machining material out from the spokes to give an “I” beam design. To top it off, these wheels feature massive brake clearance which allow them to clear OEM PCCBs and a variety of aftermarket big brake kits that many other 18” wheel manufactures simply cannot accommodate...
