There is no such thing as overkill when it comes to tire, IMO. Get the widest tire you can on the thing. That's why all the dedicated track guys are running as wide a tire as they possibly can... maximum grip.
The NISMO should be faster than a Sport on a road course. More tire and more rigid. And at a track like VIR the aero enhancements will help. The NISMO generates 150lbs of downforce at 75 mph, which is not insignificant at VIR.
