I'm getting tired of this. Am I doing something wrong?

I have a '99 SVT. I replaced the factory SVT wheels with 17" Borbet's (looks great btw). Maybe 200 miles went by and I started to get the dreaded warped front rotor feel in the steering wheel. I thought OK, maybe the OEM rotors are not up to it. So I dropped some coin and got some nice rotors from BAT ($89) with the Mintex pads. WOW!! This car has some brakes!! Well now it is 1,000 miles later (mostly highway) and the warping has started again. Yes, I have torqued the wheels down (95lb) each time the wheels have come off. What in blue blazes is going on? I've never had rotors warp like this car. Any ideas?
