I had an 87 Rx7 and I have to assume it would easily damage any NT eclipse. But the best thing to do is go race the damn thing, and tell US which one wins

As far as whatever weight ratio you are talking about? I have no idea what they are talking about. The cars are nose heavy anyway, and you typically remove weight from the front of the car. That would help the balance, not that it really matter anyway unless you road race or autox. Poeple pull weight out of these cars all the time and it does nothing but good things. If you consider crank windows, manual steering, no cruise, no AC, and small brakes "good things"
