I'd be more worried about the trans IMO. Does it launch peg-legged or with both tires? You could upgrade to a Quaife LSD, I haven't heard of an auto breaking a differential yet.

Your axles will be good to about 550-575 RWHP, beyond that with drag radials or slicks you will want to upgrade to a Getrag, or do better axles with you std rear. Also you do not have an LSD in your car as it sits, that would be a worthwhile upgrade as well...what are your longterm power goals?

Yes an LSD would be a worthwhile upgrade.

You can do this...and stay with your stock pumpkin/gears and axles
Quaife ATB Helical LSD Differential 06+ Charger, Magnum, 300 SRT8 6.1L

Or you can do a complete Getrag system which comes with gears/LSD and new axles, this would also be a good option if you intend to do a different gear as there are 3.73 and 3.92 options here, or you can stay 3.06.
