Suspension

Has anyone ever had a problem with there rear suspension when there are 2 adults sitting in the back, there is no room between the top of the rear tyre and guard. Its constantly rubbing the tyres. I have put aftermarket rims on my car so it may have something to do with that.

If anyone has any ideas of what type of springs/shocks to buy because I rang up a suspension shop and not only did they never hear of an SVX, they didn't have a listing for them. Could there be another type of subaru springs I can use? Please help......
