Thanks for the clear-up guys. I looked into the HS pages and found Celica [FWD] and didn't realize they have separated the newer generation (both trim levels) into the higher class.
On the contrary, an RSX Type S (being an even more aggressive vehicle than the new celica) stayed within HS. I wonder what's the rationale for that...
As for the Tsunami edition, they came with both GT and GT-S trims. No suspension upgrades. Just thinking of one because they are rare and look stunning (Gonna also be my daily not just a track car). It is not a JDM, just that very small numbers were made. (359 according to a quick google search, not that it matters much)
I dragged a couple pics and info online just for more clarification:
