The R36 has to step it up as the competition is getting close. The C7 Z06 is no joke. I like it but can never see myself in it.
The next generation tranny has to be better. Coming from an E92 M3 DCT, I was a little disappointed with the GTR tranny as it is not as fast and smooth. The M3 allow you to double click the downshift paddle and would find the best gear whereas this does not exist in the GT-R. Reducing weight would be great as well as you can certainly feel the weight of Godzilla on bends. Still amazes me how this thing handle given it's weight, the beauty of AWD.
Overall, this car is a beast and stock for stock, not much out there that can compete with it.
