Default C6 Rearend Upgrades

I'm about to put a ~575HP LS2 into my 07 and will be using it at the track quite frequently. I have a spare M6 trans and diff that I will be building up to handle this power and would like to get some input on what I can do to help bulletproof it. The car will see the track at least twice a month and needs to be able to stand up to hard launches with drag slicks. Thoughts? Suggestions?

PM Thesubfloor. He has a built tranny that has been holding up very well and a Z06 diffrential with additional weld that is necessary to prevent the housing from cracking.

I believe subfloor has an A6, taters stated he has an M6. My suggestion would be to contact RPM Transmissions and get their recommendation.

OP: Here are 2 sites to check out. http://rpmtransmissions.com/ & http://www.centurytransmission.com/home I have an A6 2.56 Diff from RPM and like it a lot. Good luck with your upgrades.

If you want the budget way, you would want to upgrade the main shaft to 30 spline and pinion gear to match. Upgrade all internal parts in the diff to C6 Z06 parts. If you have a higher budget, TR6060 and C6 Z06 is the bulletproof way to go. PM me if you're interested in a quote or the parts list.
