1) Good brake fluid. Opinions are mixed on the Super Blue. Motul RBF600 gets good reviews. I've had a lot of brake temp issues along the way as I've been sorting out my setup, but I've never boiled my RBF600. Keep in mind that for track stuff, and especially with these better fluids: flush the fluid *at least* once per year, and bleed out what's in the calipers before each track weekend. The Castrol SRF noted above also gets rave reviews, but it's even more expensive than RBF600 and I haven't seen the need to upgrade to that, yet.
2) Stillen's brake cooling kit. It's not perfect, the ducts are a bit small, but it's a pretty reasonable compromise for fitment to our car and spindles, and it definitely helps.
3)
Ti Front Pad Heat Shields - I use these in place of the factory pad-shims. They reduce the transfer of heat from the backplate of the pad to the caliper pistons (and thus to the fluid). Even the 0.5mm one can make things tight when fitting new pads+rotors, I'd think the 1.0mm would be a bit much on thickness unless you plan to shave down your fresh pads before installing.
Not directly a temperature countermeasure, but be sure you're running decent track pads as well, and the right rotor can help too (better cooling vane design, etc).
