Neuspeed tie bars and strut bars are cheaper than others but are just as good. It's cheapest to go with an 22mm OEM ITR sway bar on the rear and a 24mm GSR bar on the front. For the rear you'll need a reinforcement kit like the Beaks or BSQ kit. Actually you can get by without replacing the 22mm front sway bar (I'm assuming you have a G3 LS, GS, or RS) Apart from that you can get your rubber bushings replaced (time consuming and costly) with polyurethane.
