100 more hp should have no problem outweighting the 150 more lbs. However, why on earth do you need 19/20 inch wheels?...Put on a set of 18s and save urself 50lbs unsprung weight.
Why add a root type supercharger just to get 100hp? You could have change the cam and fine tune the air/fuel ratio and get more than 100hp out of the LS7. If they go the NA route, they would have maintained the perfect 50/50 balance instead of the nose heavy 52/48.
The price tag is absolutely ridiculous...90-120k?..Oh comeon. I bet at least 20k of the price hike is caused by the braking system. I don't see there is anything wrong with the ones on the Z.

Tom Wallace, vehicle line executive of Performance Cars, described driving the ZR1 as simply awesome. "It's fast and refined," he confided, adding that it has "a soft clutch, great midrange torque, compliant ride and brakes that don't squeal." He alluded to an expectation that the ZR1 would beat a Ferrari F430. Not just talk, as Tom races competitively. Pricing hasn't been announced, but we know buyers are lined up around the country. We've called the Z06 a budget-minded supercar, so the ZR1 is likely to be a reasonably priced exotic. We'll venture a guess between $90,000 and $120,000. And at that price, the performance is sure to be a steal!
