'88 GT Castor: How much is possible and how much advisable???? (Page 2/2) Rickady88GT JUL 16, 12:03 PM quote Originally posted by Will: Steven Snyder has converted to power steering and fully adjustable upper control arms. He's running 12 degrees and said it gives great grip and feel, but the outer tie rod end is high enough relative to design that it's giving some bump steer problems. Steven took me around Buttonwillow raceway few couple laps. A lot of fun.
