Rule no. 1 on the racetrack:
Don't lose time unnecessarily.
Transmission.
We have certainly kept to that
rule, as the six-speed manual
gearbox in the 911 GT3 models
has been designed especially for
the high demands of motorsport.
This lightweight gearbox is highly
efficient and the gear-lever throw
is short and precise, enabling fast
and accurate gearshifts. In con-
junction with the friction-optimised
cable pull shift, the gearbox
provides an extremely high level
of precision and capacity. Unlike
the 911 GT3, which has a dual-
mass flywheel, the new 911 GT3 RS
uses a single-mass flywheel. It is

lighter and therefore increases
engine dynamics. The engine
turns even more easily in its
upper speed ranges – with a
somewhat higher noise level.
