I've been down the boiled brake fluid road before. When that pedal goes to the floor, it gets your attention real quick! My '90 911 had brakes that were too small for my track uses. Cooling air ducted into the center of the rotor & Castol SRF solved the problem. You won't find a better brake fluid, period. Porsche runs it in all the factory comp. cars in fact, I just bought a Super Cup & that's the only fluid it has ever had in it. Like Michael, I have mixed emotions about the drilled/slotted rotors. Drilled rotors will eventually crack & the slotted ones will wear pads quicker due to the slot edges. I think I would try cooling & SRF first and stick with solid rotors. My 2 bits.
