With this car unless you can get your hands on a good supercharger, I'd say get a Gruppe M CAI, UUC Corsa full exhaust, an LSD, a good set of coilovers, upgrade your brakes/rotors/wheels. The DINAN tune/throttle body won't get you much for the amount of money you will have to pay just to have their name. I find that this is a great car for daily driving which is why I ended up getting another ZHP to put in my garage among the other rides I already have... it is just that good...
