I think Tein CS would be a good one. I know JIC is nice for VIP looks, but cost wise, too much. I just put on Ohlins coilover on my GS and I don't recommend it at all because it's a old set up with very difficult to adjust. If I have a choice again, I would go for Tein CS. As for spring, go with Eibach. Do not use Intrax because I used to have it on my 93 GS which I sold while back. Intrax will give you a lower ride and nicer look, but it is too soft for the heavy GS.
