Given that the NSX with similiar size wheels 18x8.5 and 10s' and same tires, similar suspensions mods, it will be significantly faster than even a Stage 3 TT, by the 5-6 lap it will become even more apparent as the 400hp Z overheats its brakes. Not to mention pushing a Z at 9/10ths the superHicas will definitely add to the excitement. My buddy(NSX) and I would roadrace occassionally, as i would gain a little in the straights his 600lb lighter car with similar size wheels would pull me on the twisties.
