Just remember not to make a stop from 100 mph as you park the car, and your rotors will last much longer. Try to cool the brakes for 1/2 mile or so before parking (don't go sliding into the parking lot sideways, grab the e-brake and run into work when you are late), if you park the car with the rotors at elevated temps, you can create a condition where they are likley to warp. The part of the rotor that's under the caliper will cool at a different rate than the rest of the rotor (the pads hold heat in and block cooling air), this can cause structural changes to the iron that can cause a warping condition (in some cases it can turn iron into "cementite" which is a hardened derivitave of cast iron which will wear at a different rate than the rest of the rotor, eventually causing a "warped" or uneven rotor faceing).
