The 1LE carrier and axles are stronger than the old Aussie log axle...but it is NOT as robust (or heavy) as the ZL1 set-up, which must handle almost 20% more torque than the Z06-tuned LS7.
AGAIN...when GM refers to "Z/28 track performance", they are SPECIFICALLY speaking about road course action (without static or Le Mans-type starts!).
Will a Z/28 acquaint itself well at the strip? Probably...but that is NOT its intended environment...
fwiw...

Exactly! Just like the first gen. Z/28 was designed with track/road courses in mind for it's intended environment and not the drag strip. And some people were able to make the first gen. Z/28 a great drag car is spite of it's purpose built function of being a road course car, that too is likely to happen with the fifth gen. Z/28, but that is totally outside of it's original design and intended function.
