All the reviews I read before buying a 07 G35 sedan said that it was an excellent car besides the roughness in the gear stick and clutch pedal. I bought one anyway and can say first hand that it's annoying.

Now, I like that there is vibration in both of these driver interfaces, just not the amount that manifests itself above 6500 rpm, its just too violent of a vibration and its distracting when I'm really pushing the car.

All the reviews for the 08+coupe and 09+ sedans praise the additional refinement of their clutch and sticks, yet, they're suposed to have the same transmission. The engineers have modified some parts to help.

HAS ANYBODY TRIED FINDING THOSE MODIFIED PARTS AND INSTALLING THEM ON OUR CARS?

If its something as simple as a redesigned bushing or even as complicated as a whole new shift linkage from the gearbox up, it would STILL be the kind of mod that would revolutionize many of our unrefined cars. I know for one I would do it.

Even if nobody knows, could somebody point me in the direction of something that shows all the part numbers for each year car? With something like that I could analyze which parts are different and which are the same and report back. Something like realoem.com but for Nissan/Infiniti instead of BMW.

 

iv never noticed the vibration enough to be annoyed or even think about vibrations at over 6500rpms, there is slight vibration when in neutral like almost all MTs but not distracting and the clutch pedal has no vibration issues either.

maybe this is the kind of site that youre looking for Infiniti Parts USA G/L

 

The little vibration that the shifter makes at idle does not bother me.

However, after you get on the car and its higher in the RPM range, and you let of the gas (but dont shift) and let the car slow down in that gear, i'v noticed that the shifter will shake a little more violently for just a brief period. Is that normal??

 

ya thats when you introduce engine braking and since its a RWD car it does that more prominently than fwd.
