Following the success of our 18” Porsche wheels, we’re excited to release our first batch of 19” SM-10 fitments engineered for the Cayman/Boxster platform with an emphasis on the GT4 chassis. With this first round of production we focused on wider performance fitments, so we’ve skipped the generic 8.5” front wheels for now. Additional fitments for 911 chassis have also been developed and will be released in our next round.
3D laser scans of the factory brakes ensure our design clears the massive 380mm steel brakes on the GT4 and Spyder, as well as popular aftermarket brakes like the AP Racing by Essex 394mm Radi-CAL BBK.

For years, the enthusiast community has expressed a desire for a broader selection of lightweight, race-proven wheels at affordable prices. Owners were often faced with either paying an exorbitant amount of money for custom wheel solutions or significantly compromising quality and performance with conservative off-the-shelf options.
We solved that problem with our SM-10 wheel which was previously only available in 18” sizes. This release continues the expansion of available sizes for newer Porsche chassis that require 19” wheels to clear their brakes and/or rear suspension components.
This pre-order Group Buy allows Porsche enthusiasts around the world to “Gang Up” for a chance to receive the largest discount offered on our 19” wheels.

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 Race Silver finish is not available for this Group Buy. 19" SM-10 Cayman/Boxster wheels can be fitted with the OEM Center Caps.
Flow forming enables us to create high performance wheels without the price premium of forging. It improves the mechanical properties and grain structure of the barrel, increasing its strength and stiffness, which allows us to use less material and reduce weight. Thanks to our superior engineering, our flow formed wheels have a higher load rating than some competitors' forged wheels.
One of the most prominent features of the SM-10 is its advanced "I" beam spoke machining. Any excess material that doesn’t add strength is carved out from the sides of the spokes using a precision CNC ball cutter. This process is often deemed cost-prohibitive by others, but for performance without compromise we believe it's essential.
The inner lip is the most vulnerable part of a wheel because it has no spokes for support. Our Evolution line adds more material to this high-impact area as an extra layer of protection against track berms, potholes, and whatever else the road may throw at you.
We use the deepest concave face profiles we can for every application after factoring in critical clearances such as brake calipers. The SM-10 utilizes 3 unique profiles to make this possible, with the deepest concave face delivering reduced weight and a stunningly aggressive appearance.
Big brakes often require bigger, heavier, more expensive wheels, which aren’t ideal in a performance environment. The SM-10 is one of our many wheels which solve this problem. Through comprehensive 3D laser scanning and endless rounds of test-fitting, we’ve created 19” wheels that clear the factory GT4 380mm steel brakes along with a variety of aftermarket kits including the notable AP Racing by Essex 394mm BBK.
Whether it’s a day at the track or months of street driving, repeated hard braking can make a tire slip along the bead seat and go out of balance, causing vibration. We’ve added knurled beads to help grip the tire and reduce unwanted slippage.
We conducted extensive Finite Element Analysis to reinforce high stress areas and to remove material where it didn’t improve strength. The end result is a wheel with an ideal balance of strength and weight.
Track wheels need track tools. Don’t settle for wheels that require undersized tuner lugs or thin walled sockets. All APEX wheels accommodate over-sized race lugs and impact sockets to make swapping wheels lightning fast.
All Evolution line wheels are finished using a multi-stage liquid paint over a powder coated base coat. This coating process leaves lug holes, center bores and mounting pads untouched, which ensures proper fit and torque values.
The VIA is an independent wheel testing and auditing agency similar to TÜV. Many companies falsely claim their wheels have been certified, and even use the VIA stamp without permission. Our wheels have been certified, and we provide the registration numbers for every wheel. Protect yourself. Demand registration numbers from manufacturers.
Learn MoreAll APEX wheels meet or meaningfully exceed JWL load rating requirements. Some manufacturers don't meet the minimum requirements, yet still claim to be compliant. Always compare load ratings to ensure you aren’t sacrificing critical strength for a slightly lighter wheel.
Learn MoreAll APEX wheels come with a lifetime structural warranty against defects in workmanship and materials, plus a 1 year finish warranty. Exchanges are fast, easy, and hassle-free. See here for full terms and conditions.
Learn MoreCurb rash or pothole damage on the street? Make an oopsie at the track? We’ve all been there. APEX is proud to offer 50% off replacement wheels, no matter the damage. See our full terms and conditions for more details.
Learn MoreNo centering rings required. All Porsche specific 5x130mm bolt pattern wheels feature a direct-fit, 71.6mm center bore.
All APEX Porsche wheels come with our Gloss Black cap included which is interchangeable with the OE Porsche crest cap. We also offer optional red caps.
APEX Porsche wheels are engineered to be compatible with your OEM R14 ball seat mounting hardware. They’ll also accept proper aftermarket hardware, stud kits and spacers.
All APEX wheels accept OEM and aftermarket Tire Pressure Monitoring Sensors and standard fit valve stems. We offer sensors and stems as a convenient option.
