"the pro touring look"

i only added a hellwig front bar and it was a huge improvement, but to me its a toss up between the us cartool frame connectors, sway bar, and 17"s, all 3 had a huge impact on the way the car drives. with the rear im running i dont think i can run an off the shelf rear bar. actually the first suspension upgrade i did was 6 leafs with afco nylon or delrin front eye bushings and these prothane hd rear shackles with big sleeves and poly bushings, they are really hard to find, but that also made a huge difference with body roll. im curious how much of a difference there could be if i ditch the kybs for the bilsteins.
