my uncle has the Track Edition with a nismo filter system and nismo wheels and suspension. to me it seems like it has a ton of torque down low and pulls very hard up to 110 (not that i would know
) . its safe to say that his would destroy my 6, but it if you have lots of mods id say you could take one. i think they all have the same motor (vq35de?) but the track model has more suspension upgrades. anway, ive kinda wondered the same question.
