Wish I still knew a Nissan tech to see if the sport and Nismo run the same or different programming for the stability.
1010tires.com has a calculator that can give you the percentage change in wheel speed. the nismo uses 285/35/19 stock in the USA so I dont think it will be an issue.

For reference, i run a 275/35/18 on my rear axle and the speedo reads anywhere from 3-5mph faster than actual. Stability control is still functional with my setup (though it's never used on the track)
