What differential works with drag racing AND road racing?

[twistedneck]

I'm looking at upgrading to the Boss LS Torsen diff. Goal is 20min road race sessions w/o hurting the diff or over heating it. I'm on my 3rd std. traction lock rear end and those suckers seem to loose their torque balancing immediately although they work fine after that for street and drag racing.

Is there a diff out there that can handle drag launches AND help the car put power down coming out of corners?

I chose the Truetrac when replacing my traclok. It has been great and can take a beating. It is much more consistent and predictable than the traclok ever was.

Eaton Truetrac it is. Dean from Rehagen said he didn't like the way it unsettled the car locking and unlocking, but that's a small price to pay for the ability to hit the drag strip still.
