If this is a daily driven car, I wouldn't advise going with silicone brake fluid.
Truthfully, I think the stopping power is better with DOT-3 or 4.
If the car is going to sit for any prolonged period of time, silicone would be fine. I realize that silicone has a higher boiling point, but not necessarily recommended for performance vehicles.
I have silicone brake fluid in my Porsche right now, and also had it in my other Porsche as well. Another benefit is that it doesn't absorb moisture like the regular brake fluid..I've also noticed that the pedal is harder with regular DOT 3 and 4, than the DOT 5 stuff. Also, the stuff is not cheap.
Just my 2 1/2 cents..
