just some food for thought here, why don't F1, FIM, NASCAR, ALMS, Indy, and many more use drilled or slotted rotors?
3 reasons, first is those holes are the weak link in the rotors
second, those holes or slots reduce surfice area of the rotors and thus reduce braking pad contact zones.
third, drilled holes and slots were done to rotors when brake pad technology was not near what it is today and the gasses formed from the old type of pads would create a cushion of air if you will between the pad and rotor reducing braking ability. with todays pads they don't give off those gasses and don't need the holes in the rotors to get them out of there.

and anything else you can find that has a roadracing/autocross section. corvetteforum has alot of good stuff about seasoning rotors and such. if there is a forum for WRX's that has a racing part then chances are someone has posted a DIY brake duct cooler install. Jegs sells the silcone hose in 3 or 4 inch and its 11 feet long. they also sell neoprene but it doesn't take near the heat. the china rotors are OK if you season them right. they are dirt cheep and last just as long as the expensive ones. maybe 10-16 track days. get good pads though, they might only last you 5 track days though. Jegs also sells Wilwood 600 high temp brake fluid, i run that since its local and i don't have to wait 3-4 days on UPS. some of those fluids are uber expensive, $45/12oz
here is a chart of the most recomended brake fluids out for track days
