I think W is missing out of the GTR badge. W for Warp Factor acceleration .
It is possible that T is for "Terrible" brakes. I have already found out the hard way.
Even so I´m hooked, it is incredibly fast, surprisingly confortable and civilised and like wearing your p**ck on the outside of you trousers for grabbing attention, over here at least. Even the w**kers with the Citroen Saxos know what a R32 GTR is, too much Playstation ........... as long as they don´t try Playstation overtaking manouvers !
