I don't think you are going to find many suspension upgrades for this car, other than HD shocks. Your tire/wheel size will be limited by clearance issues. IMHO, oversize wheels look pretty silly on these cars anyway.

You may want to rethink this plan, you're probably talking about spending around $10K for very modest performance improvements. It will also be very hard to sell this car with these "modifications." You may want to find a more appropriate car to start with.
