I got TEIN SS coilovers with adjustable shocks on my 2003 4 door I4 auto. Love them. To say they are the best, I am not gonna make a bold statement like that. There are so many different great setups out there using all kinds of spring/shock variations. Koni, Eibach, KYB, Tokico just to name a few. I like the idea of having a matched spring/shock combo, but let me warn you it comes at a price.
