I think if the Summit gets any more power than stock then yes, there will be driveline failures. I don't know if they are going to fail stock, I can only assume they will. They did, however, redesign the shafts and added a better CV joint to accomodate the increased angle. They have tried this on full size trucks which failed horribly and that is the reason I believe these will fail as well. I am almost positive they will crumble under any more power, and brushless will most certainly kill them.
