The list of stuff you posted is the exact thing I'm looking into. I know my front end is out of whack, as I rebuilt on side. I haven't got to the other side yet. I'm sure a good alignment might net me a little something? X pipe or H pipe in my case, that would be interesting?? My tires are 235/60R15's in back. It has rallyes all the way around. I thought maybe a set of aluminum rims may net me a 40 lb loss, and it's unsuspended weight? Although I like the rallyes.
