The 911 | Chassis
PASM sport chassis with
mechanically locking rear
differential.
The PASM sport chassis is
available as a n option for Coupe
models and only in conjunction
with 19-inch wheels.
The body is 0.79 of an inch (20
mm) low er than the standard
susp ension of the
3.6-liter engin e
m odels, and 0.39 of an inch (10
mm) lower than the PASM
suspension of the S models. The
springs are harder and shorter,
and the lateral stabilizers on the
front and rear axles are stiffer. In
combination with PASM, it offers
greater comfort than that of a
conventional spo rt suspension.
The mechanically locking rear
differential further enhances
the traction of the driven rear
wheels on uneven roads and,
for examp le , when accelerating
out of tight curves. Roadholding
at the limits
of performance
is even more predictable. The
car holds its course better and
so PSM inte rvenes less often.
