How can I tighten up my steering/handling?
So I replaced all of the suspension, steering, and power steering components, but the handling still leaves quite a bit to be desired. Getting up over 65 mph is pretty unnerving, as the car has a really bad tendency to wander and feels very uncontrolled, kind of like it's floating.
I replaced everything with the exception of the drag link, strut rods/bushings, coil springs, and ps slave cylinder, as those parts all appeared pretty new or in relatively good condition by the look of them, and the place I bought it from put a new steering box on it before I bought it. I also did the shelby drop, and of course, got the car aligned. It's certainly better then it was before I replaced everything, but it's still not as good as I would like.
I've had several old cars in my day, so I'm well aware of how they handle versus a new car, but I don't remember my other mustangs being quite as sloppy. Heck, maybe they did and I just didn't have a good frame of reference back then.
Whatever the case, what else can I do to further improve things, short of going R&P? I'm planning on a 408 build in the next year, so my goal has been to get the car shored up so it can safely handle the additional power. It's not going to be a track car or anything, but I'd like it to feel stable running down the highway or between stop lights. Any suggestions?
