Need an advice from your experience Mike,
as I don't want to mess up with my perfect alignment,
and because I am satisfied with the handling of the bus,
and since I just need to make a rear ride softer,
what if I just will:
1) replace rear stock shock to gold Koni,
2) insert the rubber so-called Sumo "springs",
3) and install the rear sway bar.
Would these three things improve the rear ride on the road bumps? If yes, don't I really may not do the wheel alignment after these things installation?
If anyone also know it, please comment!
