After reading pages after pages of technical information on the engine, transmission, aerodynamic, suspension, electrics etc etc, it seems that the fine engineers at Nissan have covered every base. You have an insanely fast car thats capable of cruising at 300km/h at the same time, quiet enough to hold a conversation (dont' know why you would at that speed). It has a great set of suspension that can handle any condition with ease. The engine is up there with all the other supercars in the world. Overall, they seemed to have put together a perfect package that's going to be hard to improve upon, any alternation is more likely to disturb the balance of the car.
It seems there's nothing left to mod and if there is anything left to mod, it would be very expensive. The exhaust mods would cost twice as much now that there's two. Changing the turbos would be even more costly, as the manifold is now actually built into the turbo. Any change in the turbo would require a replacement manifold as well. That two of everything again. Going big singles is......quite impossible?? considering the turbos are now on both sides of the car. With so much electronics in the suspension, is it going to have any improvements if you change it to a more harder coilover for example? How will the electronic system adapt to that? I'm also sure many have thought about aftermarket kit designs to make the car look more aggresive. Having read some of the pretty picture Nissan put up about the aerodynamics of the body panels, how will aftermarket parts affect that.
I almost forgot to mention the wheels. The wheels are 20" in diameter with run flats which means you don't need a spare in the boot. With a wheel size this big, most 18-19" aftermarket wheels will fit but most likely won't look as good going down a size. The tyres themselves is a problem when it comes to doing any modification. Any tyres you get will have to be in 20" rubber and if you are going on the safe side, you'd want run flats as well. I don't think its going to be cheap getting 20" tyres.
Will the new GTR going to have that much tuning potential left after Nissan doing such a thorough job of it? Will it end up being like a run of the mill supercars you see on the streets? Or will the crazy Japanese tuners come up with more crazy ideas?
