    Which clutch fluid?

    I am finally ready to (hopefully) end my sticking clutch pedal and order a Tick adjustable MC. I currently use the Prestone DOT 4 synthetic brake fluid, which has a dry boiling point of 500f, and wet boiling point of 311f. Should I try to get my hands on some better, higher boiling point fluid? I am still running stock exhaust manifolds, so the master cylinder line gets very close to the cat, even with the heat shield.

    I've just always used Dot-3 per the maintenance instructions. Never had an issue. I'm thinking the poor hydraulic system in these cars is the guilty culprit and hopefully that Tick MC will help out.

    I plan on doing the same upgrade with mine over the winter.

    Here's a sticky I put together outlining the fluids to use per the owner's manual just for reference: General Routine Maintenance / Service Intervals

    I use DOT 4. IMHO its a slightly better fluid then DOT 3...which also works.
