Will my rear be ok?

I'm planning on running some ET streets this weekend at the track and was wondering if anyone has any experience with their rears breaking with stock gears, stock a4, stock everything other than just intake/exhuast. I've read a lot, but it all had mostly to do with much more heavily moddified cars so I decided to post this up and see if anyone had experience with stock cars breaking rears.

The rear does whine on decelleration... :(

You will be 100% fine.
