i had the same problem when you drove the car over bad surfaces ,you couldnt hold the steering wheel one handed the car would be all over the place ,so i bought some shocks and springs(yellow tt ones)and put them on the car mine is a na.The back height was fine,BUT the front was too high when you sat in the car you felt like you were taking off in a plane,so I took the springs off the tt shocks and replaced them with the na springs and put them back on the car WOW what a difference now you can drive the car one handed while eating a pastie now and you can go over the roughest road surface and the car goes straight.
