Default 05 a4 diff strength question

I know that the diff on an 05 is the weak link. My question does anyone think it will be OK with my car being cammed and 4l65? I am wanting to put some nt05s on the rear because it's useless under 60mph. Car made 422hp and 391tq. Has fti 3200 stall converter, and I'm wanting more traction. So drag radials OK with auto or disastrous?

The M/T's have worked fine on my 05 4L65E with no issues ever.

Dennis50NJ has been running on the track for years and I don't think he's ever had a problem. The auto is not nearly as weak as the MN6.

I think you mean abuse to the diff, because the design is the same, only the gear ratio is different. 3:42 in manual, 3:15 in auto.

The auto is just easier on the diff correct?

Many use drag radials on the auto with no damage but if you try that tire on a 05 MN6 you're pretty much guaranteed for destruction.
