I'm not even going to waste my time here... if you seriously think weight has no bearing on lap times and endurance than you are beyond help.

I've never met an HPDE instructor who so was cocky... and no road course junkie would pick a 350Z TT as their car of choice... none.

So to me you are an ignorant liar... good day.

EDIT: One thing to think over... If weight has no bearing on track performance then why do sanctioning bodies like the ALMS and Speed GT series give certain cars weight penalties to better equalize the fields when one specific type of car is dominating? Because they do... and it does equalize the various cars.
