I have been having a problem with my car. I recently went up to 18 Inch rims with a 40 series tire. And about a month ago I had 3 people n my back seat and my back seat was sitting on top of my tires. (yikes) first off would this be my springs or my struts that is bad?(uhm) And if it were my springs, could I go with lowering springs if they were stiffer then th stock springs while on the 18s? How would that affect my suspension? I'm not to keen to car suspensions, so any advice will help.
