thanks for the comments. to answer all your questions
im dropped on h&r sport springs
the wheels were about $1000 for the set (ask for cesar at wheel warehouse in anaheim 714 772-1281)
not that much weight difference (as far as i can tell from my old m6 reps)
yeah i guess it could use more tire, but i didnt want that meaty tire look, so i went with a smaller 245 rear tire (vs normal 265 or wider)
yes my old m6 reps are for sale and just make me an offer to help me clear the garage!
