You'll be ok w the 2.5 turn I think it's the one that's labeled quick ratio from Latemodel and the likes, and besides it's already in there. Did you replace outter tierods as well? How are your bj's? With a new rack you get new inner tie rods, outter tie rods are easy to do if you haven't, and replacing the ball joints with big fat moog "problem solvers" will give you a pretty tight front end. All of that in conjunction w a decent set of struts/shocks and springs will give you plenty of feel and handling on the street.
