Jeff,

Try the Euro Rotors (2 -piece).  I've just warped mine last week at Summit,
but until then they had lasted 1 year + and six schools, street driving and
half a dozen auto-xes.  They are certainly less warp-prone than the stock
M3 rotors.

Consider ducting if you are eating rotors after upgrading.  That seems to
be the real solution.
