Good performance to do what.

That contradicts your idea of wanting good performance.
The main thing for most members is the cost. Ksports will work. If you are going to get them, I would suggest getting them teflon coated or something so they don't seize up. My friend has these on his Integra, and after a year or so of having them, he tried changing the height (last time he did it was a few months prior), and the shock body on one of the shocks basically seized to the bracket. This may be a problem w/ lots of coilovers, but I've only seen this problem w/ Ksport.
For a hundred or so more, you could get megan racing coilovers, almost everyone loves these, you can find the threads on it.
For another hundred, you could go w/ spl/kts coilovers from our our sponsor splparts.com. Those are the best for the price range imo. The inverted damper (allowing larger piston size & shorter stroke) are a major plus also. I have these and love them.
For any basic driving or entry level competition, you could even probably get away w/ a good spring/strut combination. It all depends on your goals and budget and what you are doing with it.
