I have an 02 9-3 Viggen and I want to make a good car better. I want to try and make the suspension better and I would like to tweak some more power from the engine. I am not familiar with new cars as all the cars I have ever worked on are antiques, ie 58 Edsel, so I am really a novice but hey everyone has to start somewhere. Does any one have any suggestions to make? thanks.
