Gday mate
I'm not sure about the forks/eyes thing but I'll take some photos for you - I have been told that they wont fit on the gts-t due to the rear subframe assembly being different (apparently?), so I'm really not sure if it'll fit the gts-4
re ride height, usual eyebrow height is 350mm, these shocks take it down to 325/330mm depending on how many kebabs I've eaten that week, which is legal minimum in SA...
I've removed the fronts already, I'll take some photos tomorrow and post them up - will be a week before I take the rear teins out, but I can find a photo on google I'm sure
