at 4 lbs my tires will break loose at the top of first. i'm not sure if it'll happen in an auto, but it isn't really preventable unless you aren't flooring it or you have awesome tires or a really good suspension setup....basically don't bog your engine and don't peel into first either (neutral drop for you i guess)...the last neutral drop i saw parts started flying out onto the track...rough nite.
