rotor warpage issue
ok so im new here, found site from S2's cardomain. i did a quick little search and unless i skimmed a topic, didnt really notice what im looking for.
so now the problem. i rebuilt a 01 S2 because my dad loved how it felt sitting in the car and how it looked. got it running and after about 3 months, when i came back to visit, i drove the car and noticed the rotors were warped real bad. i asked how long its been like this, and he says i had no idea there was a problem [???

] . so we go out and get new rotors and pads. i put everything on, checked caliper and slides and took it for a drive. fixed it. now last week i went back again and the rotors are warped even worse again! its been like almost 5 months and they are shot.
my question is, how many of you have had repeatedly rotors warp? with how thin the rotors are, its basically useless turning them. i dont want him to constantly be buying new rotors every 4 months. unless this problem is evident with ceramic pads, which is strange to me. id like to figure out something soon so the pads dont get all crapped up. its just horrible.
