2 years is old for a fluid to be run on a racetrack - anyone would likely cook that fluid.

Once you've changed that out, I suggest you install track pads for track use, ESPECIALLY if you run R compound tires - the increased decelerative grip will cook your street pads at the first big braking event.

Lastly, remember to compress your braking zones. Use as much braking as you can for as short a period as you reasonably can-this will ultimately generate a bit more heat, but for a shorter period (and also allowslonger cool-downs between braking events).

Good luck!
