If you read my last reply I said I agreed about the CF. For the weight the roof panel saves (only 6lbs) it’s waaaaaaaay not worth it. But again, even just the brakes put the car past $80k. A loaded Z06 is damn near $80 and on the other high-end cars CF brakes are a ~$10k option. Now, the CF brakes aren’t like the CF body parts. They are about a lot more than just the weight reduction.
Anyway, how much road course stuff do you do? If you don’t think 200lbs is huge then you need to do more. And the move to 52/48% f/r weight distribution due to the weight increase is especially troubling. So the ZR1 has much more power, but it’s going to be even harder now to put it down with less weight on the back tires.
620+HP doesn’t help you stop. 620+HP doesn’t help your car transition. 620+HP doesn’t increase max lateral Gs. 200lbs less would help all of those things. The amazing brakes and ub3r high tech shocks will help make up for the 200lbs (probably even more than make up) along with the much better tires (still run-craps, but reported to have a handling optimized compound). But just think how much better all that stuff would still be, minus the 200lbs.
I’d love to see all the goodies from the ZR1 OTHER than the motor put on a Z06. It should come in ~100lbs lighter than a Z06 putting it near sub-3k lbs. And the tires, shocks and brakes would make it the ultimate track weapon.
When you start doing road course stuff you realize huge HP isn’t always the answer. Withough mile-wide slicks (which, granted you can pretty much run on a C6Z06/R1) and lots of aero downforce (which you can’t get on a C6Z06/R1 without a butt-ugly wing and a front spliter that will get knocked off on the first driveway… and even that doesn’t rival a true race car) you can only put so much down.
