Also adding the forged wheels saved rotational mass. This too adds to performance numbers. You answered your own question. Lighter wheels, stickier/wider tires and the gear ratio changes add up to the additional acceleration. Other changes include heavier duty wheel bearings which could also offer less resistance. Hard to say exactly where the new found speed comes from as it is probably a combination of it all.
It's a Dingledarm. It's there to dampen side fumbling. If your marzelvanes fumble too much they can cause total protonic reversal. It gets ugly from there. This is really the biggest problem with the new Camaro. That and the tri-pronged blivot.
