Maybe try switching to Dot 4 brake fluid if it doesnt already have it. Motul 660 is good stuff.
Edit:
I checked today, the ISF comes stock with Dot3 fluid. Which in my mind is very dangerous as people tend to take these cars to the track and Dot 3 is just not sufficient for the amount of heat those brembos can produce. Switch to Dot 4 fluid and you should be okay.
