We've told that in testing 1 second was gained for every 250 lbs lost. So add about 3 seconds to the Z07's time...7:25:77
And IF it can even get close to that number GM will kick a lot if high dollar A**!
"CHC: Speaking again of power-to-weight ratio as sort of that all-mighty watermark of performance, are there any other ways that Chevrolet could see shaving weight from the Z/28 in the future models?
AO: “Absolutely, as I mentioned, our goal was 100 pounds and have already exceeded that. We’re approximately a year away from bringing it into production, so we’re not done yet. We are always looking for lightweight materials. To give you reference in terms of lap time, you would have to remove 250 pounds to get another second on the track and have to weigh that against another tenth of a G in lateral acceleration. I can get that same second on the track.
So you have to weigh where you are going to get your lap time down and these P-ZERO Trafeo R tires are capable of a 1.05 g-max sustained lateral acceleration and we’ve already seen decel’s of 1.5 g, so we’re getting better lap times in other ways. But the 100 pounds definitely helps the lap time. We took significant chunks out as opposed to an ounce here and there, helping us on the track.”"
