Shocks - New design for 993
It looks like Porsche in concert with Bilstein has redesigned the shocks for the 993. It appears that they have inverted the shock system -
Not sure of how these will mate to the 964, but look interesting. Will see if I can grab a pic to post
Here is a copy of a write up from a web page -
Taken from the Porsche Web sight
"Front axle shock absorbers.
To compensate for the lateral
forces on the struts at high
cornering speeds, the front axle
setting has been changed to
upside-down technology together
with single-tube gas pressure
dampers. The piston rod is now
supported at the bottom of the
damper. The cartridge projects
from the top of the working
cylinder which also contains the
gas pressure cushion.
Rear axle shock absorbers.
The single-tube gas pressure
damper is installed in the
conventional position: chromiumplated
damper rod at the top, gas
cushion at the bottom. As learned
from decades on the racetracks
of this world. However, a whole
new way of thinking was involved
in establishing the damper
characteristics – bundles of small
round steel plates were stacked
together and fitted in the damper
as valve bodies. The material
composition? Well, that’s a secret"

Are these OE replacement parts or are they improved Bilstein HDs?
Per perelet's **964/993 suspension notes thread**, you should be able to fit the 993 struts and shocks on a 964 with some minimal parts to correct fitment differences.

Better find - thanks more good info.
Sounds like they are replacement parts, but not duplicates of original as the fronts are changed significantly to improve ride and stability. Kind of a factory up date, by some 20 years
