If your rear springs are sagging, then that is the only real fix. However, you may consider adjustable camber mounts as you can tune the camber for the track and for better tire wear on the street. The best price I have seen for K-Mac adjustable camber mounts is about $280 for the fronts and about $230 for the rears at turner motorsport (www.turnermotorsport.com). I hope to get a front camber kit in the near future to eliminate some of that annoying understeer.
