And be warned, someone will probably come in here and bitch that "there will be no R35 GT-R, the new on is an R36" blah blah blah.
I do not know. If it didn't improve the handling why would they have the TC in the first place?
It's about safety, not handling. TC reigns back the car when you approach the limit of traction, instead of letting the driver push the limits. It's a safety feature, no more, no less.
However, "easier to drive" and "better handling" are not equivalent things.
