Wow old thread, but Bilstein would be the choice. They are one of the only few manufacturers who can make quality suspension parts. I would certainly get them over the Tein stuff (which aren't even that great)

 

my friend has tanabe's and i think they are garbage. really bouncy ride. absolutely no dampening. I have some powered by max coilovers on the way. don't know how they are but they are for a drift set up and reasonably priced. 32 way dampening and 18kg front/12 kg rear. it should be real stiff. also they mentioned the dampening is really hard on rebound which makes sense cuz it is porbably hard as hell to compress those springs but if you do there is going to be a lot of force wanting to go the other way.
