I seriously did not expect that.
heavier
worse tires
worse brakes
less power
still beats it... what?
I honestly expected the Z06 to trump the Nismo, first off, because it's a new Z06 and it's a far newer gen of car. The GT-R has aged now, and is on late refinement stages. How it's been able to keep up with newer cars which have made significant jumps in this time is a testament to it's engineering.
If I were to buy a car around their price ranges (GT-R, not Nismo), I would go with a GT-R even though it's a little slower today. I love a more raw driving experience, but I also appreciate usable performance, and AWD performance cars for the most part deliver that more often on a every day driven road. The Z06 seems to be hard to use on a track, let alone on these shit roads around me for example. And then there's that horrid GM interior, which coming from a Evo/WRX owner, speaks volumes.
So, the Z06 would be a track car for me. Only thing is, if I want a raw, driver's orientated track car, I can buy something for half the price and "probably" over twice the fun... Ariel Atom. Not to mention that it's pay-to-play maintenance will be significantly cheaper as well. And, it's even cooler than a Z06.
