Depends with your usage. Do you do regular track runs? Coilovers would be great or lowering springs for that decent stance and ride comfort. Suspension kits plays a big role not only for looks, but also performance and handling. A know a guy who installed an Airlift suspension
kit in his lancer, he uses his car daily and also as a weekend warrior. He said its just running on coils and lowering springs in the same time.
