The extra .5" front wheel width makes the 305 a reasonable choice - that's a huge advantage even if everything else was the same, which it isn't. Then there's the '15's shorter final drive...
If the regular 370 got moved in with the Nismo in BS, I probably would have traded up. I mentioned this on another forum, which was probably a mistake, as it wouldn't have surprised me if the Nismo had been overlooked if I hadn't mentioned it.
Got a dark cloud of classing over my head, sorry it sprinkled onto the Nismo owners too
