Mmmm, an execuse to get big brakes down the road? Got to start saving up! ;-)
I've had slotted rotors (Ate powerdiscs) on my '90 CoupeQ before, didn't feel any difference at all, and they warpped the same as new blank rotors. I don't think slotting helps cooling much, it's the internal vent design and brake cooling ducts that make the biggest difference.

Sorry for the delayed reply. S4s are known to have front brakes that warp
easily...probably because they don't cool very well. Mine warped by 30k
miles. Dealer resurfaced and they are fine now. But, resurfacing will
probably decrease the time it takes for them to warp again. Best best is to
replace with slotted rotors ($100/ea I believe) and get some aftermarket
brake pads (Mintex, etc.).
