just you.
OE sizes.
To your point, the Corsas DO look better on the wheels. The squared off nature of the Pirellis look very race car. No doubt.
Debadge as well. No 'Z28 badges' anywhere except the wheels and calipers.
Oh, also added the OE amp, sub and the door speakers. The sub does add weight. i bet that thing is 10lbs easy.
