Brake upgrade questions

I took my car  to Thunderhill in Jan. for the Audi club function. I did 
not have any problems with my UFO's. In reading about problems with the 
UFO's they tend to create the warp when coming to a stop hot. I made a 
point of using the cool down lap to ride around w/o touching the brakes 
unless I really had to and  I would go for cruise down the road to cool 
the engine and the brakes down. I also try not to come to really hard 
complete stops when I will have to sit at a light with the brakes 
applied. This tends to cool the rotors unevenly causing the warp 
problem, if I have no choice I will pull the E brake and release the brakes.
So Far So Good
