Why is the new ZR1 so heavy? I know it went up an inch in tire size front and back but the lighter rotors should have compensated for that at least a little bit.
Also, I read that the tranny is built to handle the power. Does it have the T6060 of the Viper?
Disregard both questions.....I did more research and found my answers. This car is far more than a souped up Z06. It's a built supercar, ableit with leaf springs.

The leaf spring design, as used in the Corvette, is actually superior to coilovers in some ways.
If you don't think so, then ask Reeves Callaway*, or ask Pratt & Miller why they didn't use coilovers on their C6RS. And I'm not just saying that. I'm serious. Call them and ask.
After all, we're not talking about the stacked leaf spring design found on a truck.
*"We do not put the full spring loads of the suspension through the shock towers. First they were not designed to carry those loads, and second, we used to do that with our earlier versions of the Coil Over theory of how to make a Corvette handle well. Long term, it was not a success."
Yea but if you listen to the Euro mags the leaf spring has gone way of the ox cart. The leafs seem to work IMOP,but I am not an expert like the euro mag are.
Supercharger and upgraded drive line parts add the weight. However, 3344# divided by 620 HP = 5.4#/HP! The 620 HP is with a J-1349 correction factor. If you use the J-607 correction factor (the one aftermarket advertisers use) the HP will go up 30-35 HP. 3344 divided by 650 HP = 5.15#/HP. My Katech Z (which I will keep) weighs 3155# and the weight to HP ratio is similar to the ZR1 depending on which correction factor you use. But, I think there are a lot more good things to come out about the ZR1. Maybe Zippy will give us all a ride when he gets his? Maybe he will at least let us look at it?

That hits the nail on the head, IMO. As I've stated here before, I feel the ZR1 is essentially a public test mule of sorts. Technology used in the ZR1, supercharging for example, may likely find its way into future Corvettes, starting with the C7. We already know from seeing the GM LSx roadmap that most future LSx engines are going to employ supercharging. In addition, I wouldn't be at all surprised if the C7 is E85 compatible. In fact, I wouldn't be surprised if the ZR1 also turns out to be E85 compatible as well. Since Ethanol blends are a higher-octane fuel, forced induction can benefit from it (fewer cubic inches + more boost = less weight along with increased hp and fuel mileage), so it only makes sense.
Think of it as an evolutionary change. Remember, Mitsubishi already had the same idea.

How do you get the less weight? Super charged engines are heavier and taller and neither are good for performance cars today. Maybe with improved supercharging technology but not today. The Ferrari engine is so tall it must go behind the driver!
Also, E85 is more expensive to produce that gas. I don't see how that is going to change. It is only successful today because of government subsidies. However, GM and Katech both have powerful e85 engines.
