How much will adding 16 lb to my car affect ET/mph(rotating weight)

agree that we are all ways looking to improve on our ET.
But i would spend the time to remove my interior before i started scraping undercoating.....which i'm not willing to do.

I didn't loose weight, i gained weight. Why? Because i needed a DOT tire to go racing and theses tires, i had kicking around and cost me zero Dollars. And in the end(although wasn't my original intention) allowed me to do some tuning to my suspension.
