Well each to their own but I personally try to avoid anything GTR for my car......just dont wanna make it look like something its not.
The only GTRish styling ill have is the bonnet, but it's made specifically for the GTT ie no need to change the latch or the hinges..
Speaking of which you will need to get one of these bonnets or a genuine GTR bonnet cause the GTR bonnet is shorter than the GTT one, if you go the genuine GTR one than I think you may need to change the bonnet latch and hinges.
Other than that its front bar, rear bar, front and rear guards and then of course rear diffuser and also the red reflector on the right side of the number plate and the rear wing.
All in all its not worth it if you wanna get genuine parts cause once your done you probably could have afforded the real deal if you traded your car in.
