My '02 SC430 has a distinct shimmie starting at about 60mph. I had the front end aligned without improvement. They advised me to switch rear wheels to front and align them also. Has anyone had this same problem and if so is this the fix? Homer, in Goodyear, AZ (1st time user)

 

Try posting this on the SC430 forums..You have posted this in the classifieds and probably wont get any response here..
