This is a pretty straight-forward install on the G35 Coupe. The one thing I recommend, as I found out, is to remove the catalytic converter brace (it\'s 4 14mm bolts total), and it adds a lot of room to work. Also important is to use a 10mm pipe wrench to avoid completely tearing up the clutch line that stays with the car. Finally, I recommend using Nissan OEM DOT 3 brake fluid. (Z1 Recommends Motul RBF 600 Fluid.)
Before and after impression is extremely positive. I noticed when removing the OEM clutch line that it was heat shielded. Upon pulling the heat shield off, I noticed degradation of the rubber. Definitely not a good thing. I can easily see how, especially when hot, the rubber would have expanded when pressure was added, negatively impacting clutch performance.
First thing I noticed was that the clutch play from the top of travel all the way to the floor has been smoothed out. Feels extremely linear now. I took it for a quick drive and was immediately impressed with how much easier it was to feather out the clutch. Before it was much more stop-start, with not much in-between. Now I can start the car out much easier and definitely a lot more gracefully than the herky-jerky starting I\'d been experiencing.
My biggest gauge was on the first drive, wide open throttle, shifting from first to second with VDC turned off. Before I would get a nice little chirp when I hard shifted from first to second from the rear tires. First time out with the new clutch line, the rear end got a little squirrely when hard shifting, but quickly regained composure.
I feel that this $29 modification has given new life to a clutch I once believed was on its way out. I\'m really looking forward to a long drive with the car in the near future to fully gauge how well this clutch line has worked out. Definitely money well spent.
