LOL so you just asked if you can customise a GTT to look like the second picture but then you state that both are GTTs.. im assuming you are some 15yr old kid with high hopes..
simply put the 4 door have different rear end to the 2 door.. lots of differences, diff boot, light housings, etc.. so will be costly to do
the reverse lights down the bottom are standard on GTT Coupe (as the second pic is a gt/gtt as the GTR has a red fog light) it looks like the owner has stuck some sort of cover over it
