Who has metal motor mounts on their 996 TT. I initially went to hard rubber mounts but then to metal motor mounts and PSS9, the rear of the car is is VERY solid ?? Probabaly good for track days but I don't ??

 

You don't want to put solid motor mounts on a street car. You might be thinking of the Wevo semi solid mounts which are much stiffer than stock or the x73 mounts. Also you'll need to change to the 997TT tranny mount as your stock one will fail if you just do the motor mounts.

 

I knew that solid mouts could cause some issues with knock sensors due to the lack of high frequence vibrations dampening.

 

These are the RS versions which Gert at Carnewal offers, they are are in fact not fully solid you are right guys, just the very stiffest versions
