Go to treehouseracing.com and get there fcab and rtab kit.. better than powerflex by far.. then get bilstein coilovers and a bmw performance strut bar.. then get a hothkis sway bar with endlink package.. you should be good with that.. you might not be fond of bilsteins for some reason so look into h&r's maybe? search the forums..
and btw congrats on the aa s/c thats my goal over the summer.. what blower did you get? and plans for stage 2?
also you dont have to get coils.. people run setups like mine eibach springs bilstein shocks with some heavy duty bushings and a sway bar and you will be good to know.. wait for more people to chime in because every1 has there own opinions and there alot of knowlegable people on here.
