^^ out of everything I've installed so far suspension parts have made the most noticeable changes. The front K member, coil overs & SFCs are improvements I should have started with. So many are focused on increased HP and sure that's a big piece of the puzzle, however suspension upgrades IMO give you the most bang for the buck. Keep us updated on your GTS and hope to see you at an event to check out your ride in person.
Cheers
Andrew.
