I am a expert on rebuilding axles as I work part time with one of the best axle and driveshaft re builders on the east coast. What exactly is snapping on these axles. There are only 3 parts to a axle, the shaft , the race and the cage. It is almost impossible for the shaft to snap so that leaves two.

C8Jake tanks for the usual dumb comment! 2,700 C8's on the street now. 1% of people are probably the only ones pushing the C8 which brings that 2,700 number down to 27 C8's that are being pushed. That's a 4% failure rate of a sports car being driven like a sports car in about 3 months or so after being shipped. Add wear and another 9 months and we'll probably be looking at a 12% failure rate.
Add more horsepower and the number goes up even higher. Hard to believe that after "years" of testing GM didn't notice that their axles were failing....
Breaking axles is cheaper then breaking tranny like the GTR did back then?
You left out the rest of the story. Nissan said it was because the owners used the factory installed launch control and that was abuse (shouldn't have been used) so the $20k gearbox was on the owner. Then later they lowered the launch RPMs. Peeled the splines off the input shaft like an onion.
Yeah, maybe the owner should realize it's designed to be a sports car and not a drag car. Launching at the drag strip with low tire pressures and the grippy track surface puts way more stress on the car than launching on the street with recommended tire pressures.
What I don't want is GM beefing up these axles and adding the worst kind of weight to the car: rotating and unsprung.

The primary torque limiter is the tires. The next is the clutch and then engine torque limiting engine management. Electronics can instantly cut the spark to the engine and slip the clutch if the tires have too much grip. The mechanisms are in place already. The axles are probably the best fail safe mechanical mechanism next to the tires though. Dragging and burn outs are not my thing.
We don't have all the info in the least, they may have had low tire pressure on drag radials and coming out of a water box and then sudden hook on dry prepared concrete. Just go to Youtube and watch the videos of all the Challenger diffs exploding in this same way as described. There is nothing made that can't be broken given enough abuse.
Maybe, however when the axle gets upgraded what's the next part in the transmission that will fail?
What ever it ends up being you can guarantee that it will be expensive and a PITA to get to. If you need to have a weak link, I could think of worse ones than the axle shaft.

not the tranny just more tire smoke....lol...Z version and 2021 models will be upgraded if needed...pay to play also comes to mind...Mass produced street car (except for this year) not dedicated 1/4 miler...jmho

The 2nd snapped axle I've seen!
