Agree w/Shosholoza. I made the same mods and it solved the problem. Also recommend Padgid Yellow pads for the front for track days. Big difference and they last a long time.Yes - there are many threads on this issue.
The quick fix is to replace the brake fluid with a higher temp brand. I use Motul 600.
The next quick and cheap item is to relace the stock brake ducts with GT3 ducts - they cost $30 and simply clip in.
These two mods worked fine for me, running 30 minute sessions at Sebring in summer.
