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.
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
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.
