got a 88GT so far i have installed eibach pro kit, steeda strut tower brace, 2 point lower brace, full lenght subframe connecters 4pt, upper and lower control arms, welded torque boxes etc.. replaced wheel bearings, and bushing in the front with polyurethne bushings. the steering has some play in it when you move the wheel it moves a little first before the car moves and makes a humming noise when doing so, i replaced the power steering pump already. what can i do next to make it handle????
