Soft clutch at the track

[Zolid]

I recently went to my first track day with the NISMO on friday (Sept. 4th). The track was a 2.5 mile course and I was able to do 5-6 laps before the clutch got so soft it would hardly even come back up. I'm assuming the problem is the clutch fliud is boiling. Does anybody else who tracks their NISMO have this problem? How did you fix it?

Other than the clutch issue, everything else was working awesome. I just need some better track tires.

same issue here... I had to pull up the pedal with the left foot before being able to use it again.

flush the stock fluid completely with RBF600 and try to put some sort of heat shield between the clutch hose and the left kat.

Thanks, I think the next time I go i'll try the RBF600, I didn't realize brake fluid and clutch fluid were the same thing. I'm also thinking of replacing the stock rotors with some drilled/slotted rotors and some aggressive pads.

I think the stock brakes are actually quite good. If your going to be doing track days save your money for more tires

big mistake... drilled/slotted doesn't give you anything better than plain rotors but a headache when they'll crack.
use regular centric plain rotors and save the money to put some braided lines, good brake fluid and some DS3000/ XP10/XP12 brake pads.

The NISMO clutch is the greatest clutch know to mankind. It cannot be improved.

change the fluid... I don't know why.. but that was a nice added bonus when I swapped my fluid. (and a better fluid is beneficial anyway)

okay ill try that, is there any special kind i should use? and also after i got done driving it today, there was a brown fluid on the ground is that the fluid?
