I can not tell you for a fact that by going with a slotted or drilled ventilated rotor will stop fade. Are your rotors not ventilated now? If so then slotting them will have the same effect (in so far as fade) as getting drilled rotors. This 'wipes the fire band'. Of course a slot in the pad does the same thing (ever notice that a lot of pad have a slot cut in them?).

$3000 for four wheels installed makes sense. You didn't mention the fluid. What fluid are you running and is it changed out completely before every track event. Many of our master cylinders are vented to the atmosphere and brake fluid absorbs water quickly. 'Wet' boil point is significantly lower than 'dry' boil point. Once a can of brake fluid is is been open for 30 days it isn't worth anything but maybe your hydraulic clutch.

Stopping a car is converting kinetic energy into heat. The 'big' brakes are more fade resistant simply because there is more mass to heat up. Any thing you can do to cool the brakes faster will help but it still takes time. If you decide to duct the brakes, make sure it is done correctly or the rotor will curve like a cup!

There is no hard and fast answer aside going with a set up that has been already proven on your car in the environment that you intend to use it in.

Be aware that the Wilwood brakes do not have dust shields to protect the pistons from dirt. They should be rebuilt every time you change pads. Cost will be about $100 each.

It is a tough problem to work with if you don't want to just drop the bucks.
