I've got an R34 GTT coupe myself - the front shocks from an R33 GTS-T will fit, as they're both eyelet types, however the GTS-T rears are also eyelet meanwhile the GT-T's coupes are fork types.

I can ask regarding standard shocks for the FAST codes, however I'd suggest getting the Bilstein shocks pointed out in the the first thread post.
