While in traffic the clutch pedal was not retaining pressure and would stick close to the floor requiring me to kick it back up with the top of my shoe. After reading the message boards, another common 350Z issue is for old hydraulic clutch fluid to go beyond its heat rating, forcing the OEM rubber clutch line to expand in stop and go traffic. This would occur due to the positioning of the clutch line next to the exhaust manifold. Both issues were causing clutch pressure to drop so it was of to the shop to have this taken care of. Greg at Specialty Z had the master cylinder ready for me and I purchased the stainless steel line from Techna-Fit, a high quality local builder of “fluid delivery systems”. Greg wrapped the line in heat-resistant tape for an extra measure of security, bled the old fluid and replaced it with ATE Super Blue high temp hydraulic fluid. The difference is night and day with the pedal travel allowing me to smoothly transition from one gear to the next.
With these minor mods I have increased the performance of the Z by creating a more robust clutch system allowing me to push the Z a little harder when the time calls for it. Well that’s it for the drivetrain mods; lighter flywheel, performance clutch, stainless steel clutch line with heat shield along with high temp hydraulic fluid. I’m now ready to focus on other areas of concern; brakes and engine management.
