I've seen a 650hp bolt C7Z, A8 car break a CV shaft at the track, no wheel hop, just broke on the hit.
Usually they break spider gears before the axles though....Unlike C5s/C6s, which usually break the stub axles in the diff first.

Supposedly RPM transmissions has the Quafe diff conversion prototype done, I doubt its on their site yet but....Its coming and supposedly works with the electronics....(although the electronics aren't actually controlling the posi anymore).

He called me we talk for at least 20 mins very nice guy from what I see from pic's and that looks ton stronger for sure. told me price was from 1200.00 to 1500.00 for labor & parts..
I did the wavetrac from RPM Todd & Rodney great people...

as a follow up to this, i went ahead and changed mine and feel it was a good move, the same weekend two other high powered c7 autos broke axles ending their day.
