fair enough on the exhaust, as for the suspension i've got koni yellows with just a coilover sleeve on my car, but if you are serious, starting from scratch and want really good handling, you probably wanna swap in some dc2 parts and go for some proper coilovers (anybody seen DA specific coilovers?) do a search cos i know its been covered here before. try simota for the intake, www.simota.com.au and just make your own cold air feed.
