First of all, respect for wearing down the HAWK pads. I understand that track driving really punishes brakes, but I've had mine for 1.5 years and not been easy on them and I still have like 75% life left.

As for the tires, I still think the 245 on 8" is the problem. I read on the M3 forums that running 245 on 8" on our cars actually reduces grip compared to 225 on 8". I'm sure the tires would do a lot better on 8.5" or 9" wide wheels. I know that E46 touring cars run 245 square on 9". Those 200TW also like much lower tire pressures. I run 34psi on my Indys, but I've had Autocrossers tell me they run their 200TW tires at 26psi.
