I been looking around for some answers but can really get none. And i *** i must get it ere.
My friend got a set of skunk2 springs for an RSX/INTEGRA which he was converting to a TYPE R.
My questions is can those springs fit my 200sx?????

It's possible... But it's possible in the same way as getting struck by lightning, winning the lottery, and accidently f•cking Jessica Biel.

I agree. Why would you want to put skunk2 springs on your 200sx. Here is a link to the suspension article that will answer all your quesitons!
