I've seen one or two on the road. They seem alright...the cosmetic add-ons make them look nice (the ZX3/SVT 3-door is my favorite bodystyle). They're supposed to be great in the handling department too, but in the end they do nothing for me...I'd probably take a Civic Si, drop it an 1.5" and put some respectable rubber on it.
But that's just me, to each his own.
