18x8.5" ET42 APEX SM-10 Porsche Wheel

"I" Beam Spokes

This is the most significant new feature we’ve added. Weight is reduced by CNC machining material out from the sides of each spoke. It’s expensive and avoided by almost every manufacturer, but we’ve made it affordable through volume production.


Beefier Lips

By saving weight elsewhere, we’ve added extra material where it counts. We beefed up the barrel’s inner lip to better handle the abuse from the street and track.


Factory Support

Like all our APEX wheels, The SM-10 supports all OEM hardware like OEM Roundel center caps, wheel lugs, valve stems, and TPMS sensors. No centering rings are needed either.


Concavity

Multiple face profiles are utilized to maximize spoke concavity and reduce weight on the SM-10 design. To maintain our great brake clearance the profiles and spoke curvature of this wheel is just like our EC-7 design.

The APEX Standard

FEA Optimization

We took more time than ever before on this step, revising and iterating our design to reduce weight as much as possible. After countless iterations we removed material from the sides of the spokes in a way that allowed us to increase strength over our previous designs.


Always Flow Formed

All APEX wheels feature Flow-Formed construction that utilizes rotary forging to produce a strong and lightweight barrel. The SM-10 is no exception.


True JWL & VIA Certification

You won’t find tricky terminology to cover up a lack of testing here. We always do real world crush testing and get real certificates from the Japanese Government again to prove it, just like we’ve always done.
