Their times for the GT2 are 7:24 for the RS (as you noted) and 7:32 for the "vanilla" 997 GT2 that pre-dated it.
You are incorrect, the Sport Auto test is with a 2011 GT-R. the 2012 has additional upgrades and performance improvements over it.. http://www.nissan-global.com/EN/NEWS...1107-01-e.html

Your tire assumption is incorrect too. The Sport Cup N-spec that is used on the GT2 RS is 80 treadwear and classified as "Track and Competition" tires. The SP Sport Maxx GT 600 DSST CTT on the GT-R are 200 treadwear "Extreme Performance" tires comparable to say a RE11 or AD08. Not in the same league at all.

As for "street legal", just about anything can be street legal. These Hoosier slicks are DOT approved for street use too. At 40 treadwear, it won't last you a month of daily street driving.
