here ya go... try this...
for handling...
1.) Konis, Konis, Konis, I cant say it any better
2.) GCs, GCs, GCs, or if you dont want adjustablitiy, you want something preset, I recommend the H&R pro sport progressive springs from
www.spmotorsports.com Very nice!! I have them, with 17's and no rub! and the ride handles like a dream from stock,... just ask carrot_top(hello curve in VA goin to the meet!!

)
So your best bet is to go with Konis and H&Rs with 17's with a 215/40-17 tire!! that is what I have, minus the Konis(yeah, im still kickin myself in the arse for that one!)
now for sound...
1.) I give you hands down props! I have always wanted to do that, I sunk over 2grand into my sound stereo!! so Go ahead, I wont disown you!
