► APEX | New PS-7 Wheel Design - Concave E9X M3 Fitments

New Release: APEX PS-7 lightweight wheels for E9X M3

The APEX PS-7 is the first of a new line of lightweight, street-focused wheels arriving in June in BMW-specific fitments. The development of this new line will allow us to continue developing track and race-specific designs separately, while also bringing our expertise and lightweight technology to the typically heavy and aesthetically focused street market. The PS-7 brings long needed improvements to a mesh design that’s been seriously lacking in features, and left enthusiasts with only heavy alternatives.



Just like the rest of the APEX wheel line, the PS-7 is once again produced using the Flow-Forming manufacturing process. Flow-Forming, which has also been called “Roll Forging” or “Spin Forging”, produces a barrel with similar strength to that of a fully forged wheel. This significantly reduces weight in the most significant part of the wheel, as it has the greatest impact on rotational mass. Even with key strength improvements that add weight in select areas, static weights are reduced by 20% on average versus cast alternatives.

More aggressive wheel widths and offsets were selected versus our line of race-oriented wheels, allowing for a flush fit without spacers. Initially available in 18” and 19” diameters, the PS-7 is produced using three unique face profiles with increasing spoke concavity. We designed these these face profiles to significantly increased concavity on many applications that are traditionally more conservative. A total of 17 BMW specific sizes in three finishes are initially being released.

Strength improvements were made to help specifically address the unique abuses of the street where low-profile and stretched tire fitments are used. To help fight wheel bends, we’ve increased the thickness of the wheel’s inner lip. Load ratings exceed JWL requirements, and all sizes have been crush tested in Japan, earning them official VIA certification and registry marks. Additionally, the barrel’s diameter increases sharply after the drop center, improving big brake kit clearance. The PS-7 also accepts OEM Roundel center caps, TPMS sensors, and comes with our newly redesigned gloss-black APEX center caps.

Performance luxury vehicles deserve much more than heavy cast wheels. The PS-7 combines racing inspired lightweight engineering with desirable street styling, to produce the ideal wheel of choice.

Group Buy Pre-Order:
Pricing and discounted pre-order details will be released the week following Bimmerfest. Follow us on Facebook or check back here for sign-up and participation details. Orders will begin shipping in June.

If you are attending Bimmerfest at the Rose Bowl in Pasadena, CA this weekend, come by to our booth to see the PS-7's in person. Our team will be there and would gladly show you the new wheel.

You can see the weight if you're on a desktop. I'm guessing a smart phone app might miss this, assuming you're on a smart phone?
