Whats this like on a classic?

I want to change my Tein Coilovers and get something slightly less harsh.

what year STi should i be looking for?

whats my Tein stuff worth? (it has adjustable top mounts)

STI 3-6 (any GC8) (i've asked about this as i have very harsh Jap spec coilovers)

Depends what Teins you have as you can see from this TEIN U.K. | PRODUCT (http://www.tein.co.uk/product/index.html) they do a lot:)
