I would like to convert the suspension of my Aero to that of an SXT. Can anyone tell me whether this would be dangerous or foolish? My assumption is that I could replace the shocks, struts, and springs — and that's about it. The goal is (a) to stop the car scraping on every incline and (b) to get the nicer ride of the SXT and up. The Aero has a very stiff suspension. Does anyone have any thoughts on it?
