You can easily adjust the clutch of a G35 sport coupe. I've done it twice on my cousin's black on black G.
I've done it to my WRX as well, as it came from the factory with overly high clutch travel and engagement.
If you look underneath the footwell, you'll see that the clutch is attached to a metal fork, held in place with a rod with a hole drilled in it and a cotter pin (looks like a bobby pin). Take out the pin with a set of pliers, then remove the rod.
This is the hardest part: you need to get the metal fork out of the confines of the clutch pedal. The method that worked best for me is to pull up on the clutch pedal while simultaneously pushing down on the clutch fork, then moving the fork to the side of the clutch pedal. This is the most aggrevating and time consuming part of the whole process. Don't be surprised if this part makes you curse and spew expletives about the engineers that designed this part.
After that part is done (:oface whew), use a 10mm wrench to loosen the nut behind the fork.
To adjust engagement and travel:
turn fork CLOCKWISE ---> for lower engagement and shorter travelturn fork COUNTERCLOCKWISE--> for higher engagement and longer travel
I had to adjust a total of 4 whole clockwise turns for my cousin's car. (I suggest trying 2 clockwise turns, then seeing how the car feels. If you want it lower, just repeat the process.)
After you adjust the metal fork, it's time to put everything back together. Tighten the nut behind the fork, then shimmy the fork back into place around the clutch pedal. Re-install the rod and the cotter pin, and take it for a spin.
When I took my cousin's car out for the first time, I felt like I was driving a truck with its looooong clutch travel. After the adjustments, it now feels like the proper sporting car that it is.
