I want to lower my Si about 1-1.5 inches. I have 225/40/18s on it so I want to make sure I have now issues with rubbing. I want the front to be level with or lower than the rear. I have seen some cars where the rear end looks lower than the front. If I go with spring will I need a camber kit for a mild drop no more than 1.5 inches? Can anyone give me some good advice?
