So yea,

Just wondering what the differences are betweem the 34 GTR and the 34GTT since not much seems to be in it?

Pumped guards, bonnet, front bar, rear bar?, side skirts?, rear wing, different badges (hehe) that's about all I can think of.

looks can be deceiving..panel wise pretty much everything is different as mentioned above..GTR is the big brother on steroids compared to the GTT

Here you go, this site should explain most if not all the physical differences..use a google translate if u can't read jap:
