A known weak point on all 3 series and 3-series based vehicles
is the rear upper shock mount and the mounting location.
Performance dampers exacerbate this problem, and it can be
For whatever reason, this shock mount area is something BMW
never got right on the three series from the 1983 until the 2007
modes: the OEM mounts are sloppy and fatigue quickly and the sheet
metal area around them can be deformed over time simply by
absorbing road irregularities. The stress high performance shocks
can apply to the chassis has been know to cause permanent damage

There is nothing to be scared of here - we have a
Many companies make an upper shock mount, but we couldn't find the
best out there, so we designed our own with fgeatures we liked from
the ones already on the market to Make the best. We make, what we
believe are the best performing solid-mount RSM you will find.
Structural improvements and quality in these sets are dramatically
better next to other "high performance" shock mounts.
Many other mounts (even many performance mounts) are too
compliant to allow the shock to receive the feedback from the road
surface for top performance from the shock. They may actually
hinder the shocks ability to do its job. The common misconception
is that without compliance in this area, the shock cannot do its
job; this is not the case. Passing the most accurate amount of road
feedback into the damper allows lighting fast responses inside of
the shock to occur. In fact, with high quality shocks, you could
use these mounts on the street, however you would hear a lot more
noise as the shock valves operate in addition to more tire and road
noise that is transferred into the cabin.
We make the best around for track level performance, supremely
responsive with a high quality monoball bearing for years of
A must have when doing rear shock upgrades for track use, these
will save you time, money, and help save your chassis.
