Weight saving!
Weight savings! I found some weights recorded for the CCB disc's vs steel brakes. This is from a C6 but should be fairly close.
All 4 CCB disc's are -28 pounds lighter but the 4 calipers add back +10.80 to the number for -17.2. vs steel
To compare the Michelin PSS non runflats in 325/275 weight 24 pounds less than the stock MPSS ZP's. Then with ZR1/C7 grand sport wheels. You save another 10 pounds so 34 pounds off the top.
The -34 pounds can be felt as the car drives seemly lighter feel.
Then my recent headers also reduced weight! Not sure yet how much need to weight the stock stuff that came off.

WOW! -34lbs. of "rotating weight" less than stock (wheels & tires) "should" drop ETs & increase mph noticeably. 
If all 4 CCB disc's/rotors (rotating weight) weigh 28 lbs. less than the standard steel rotors than I give that two for additional performance. 
Waiting to see some real track results!!

You can save 34 lbs by going to a lithium battery, around $300.

Pretty sure the AP Racing thread has exact weights for stock iron, ccb, and their setup.

Just remove the brakes completely if you're drag racing. Pull the chute and drag a foot out the drivers door. Done.

That is the true question. Do some of these costly weight reductions translate to better times at the track? What is the biggest bang for your buck. Is a less than 1% reduction in weight significant? Can it be felt in the SOTP? Same with HP gains. How much do you need to gain to actually perceive it?

So using the curb weight of a factory C7Z, 3524#, the drop of 34# via a different battery brings the new weight to 3490#. For apples to apples comparison, lets keep the HP factory, 650HP. That gives the stock 5.42#/HP and the new battery 5.37#/HP. The real question then is, how much HP do I need to add to the stock Z to get the same affect as a 34# weight reduction. A surprising 6HP! I highly doubt your SOTP meter could detect a 6HP difference on the Z.

Unsprung weight reacts differently in a car's handling. I saved ~38lbs (tires/wheels) and could definitely feel it in how the suspension responded in a track. But 0-60 you're exactly right. No noticeable difference in acceleration.
