That's got to be a record! /sarcasm

Seriously, what is the difference between the GTR fluid and the fluid in the Stock Z?

Stock is Nissan DOT 3. The GTR is DOT 4 and more than likely is synthetic and has different additives in it.

All brake fluid is synthetic.

Dot 4 has slightly higher wet and dry boiling points. Both are compatible with one another but not dot 5 (albeit dot 5.1 is also compatible with 3 & 4, but not 5).

IMO, at a minimal, dot 4 should be used in any high perf vehicle.

Lazy to read past post. Any particular year model does this problem occurs?
or what Date of manufacture? TY.

Is the CSC an issue with later models?

Hi Akmcmahon,

In this forum I've read about 2013 on down having the CSC failure within 7000 miles and some at 20 or 30,000 miles and some having that many miles with no failures. I detect no pattern and theoretically, because "race car" then power train components should not fail within the boundaries of their use (capability of the engine) etc.

Wasn't thinking when I typed that lol.

Yes dot 5 is a big no no.

The difference between dot 3 and 4 is negligible for a street or street performance vehicle. Unless you are going to track it, if you have DOT 3 in I wouldn't go run out and change it just because it is DOT 3 (your not going to boil it on the street or spirited driving). Also I believe the viscosity is different between the 2.
