Sure we have a car here that consistantly pulls 1.5s 60ft time. But once people get a better hooking tire, and a transbrake/or manual transmission - then we will really see what parts break. The driveshafts are tiny, I cant believe they have held up so long. So far we have not had even one broken driveshaft though. Axles are a proven weak link, we recommend they be replaced with anyone running over 430whp and drag radials.

500 to 550 RWHP is just the beginning for these cars. I agree that so far drive line shock and stress haven't been fully realized on this platform yet for the reasons stated. The weak links will show themselves as the power levels increase, stickier tires are used and launches become harder. 4100 lbs is a lot of mass to get moving. While on the subject of hard launches Tremec, Lakewood, Hayes or somebody needs to come up with a safety bell housing that is capable of containing a clutch explosion and will integrate with the T56 transmission. I haven't followed the T56 product line closely so maybe that has already occurred.
