05 diff grenade concerns
So I'm sure this topic is well covered somewhere on this forum, but my attempts to find the info has come up short. I have an 05 c6 Z51 A4 with an E-force and full exhaust, making around 475 at the wheels, and am trying to figure out if I should start budgeting for an 06- diff conversion. From what I'm reading it seems that typically only the six speed manuals are falling victim. I don't have any plans to add more power right now, but I would like to buy some sticky rubber and put in some time at the strip for fun soon. any info is appreciated.

2005 diff upgrade.
You can install the later design 2006> but in order to do so you will have to change out your transmission extension housing to a 2006-2007 one. Part number 19132778. This trans extension will bolt to you existing trans and will mate the later diffs.

Don't worry with an A4. I wouldn't waste another thought on it.
In any c5 or c6 Vette, if you get wheel hop GET OUT of the gas instantly to stop the wheel hop. Wheel hop is the #1 killer of Vette differentials.
Enjoy your car! It's not made of glass (it's SMC these days), they are actually extremely durable and terrific performance bargains.
