True Trac Diff??

I was considering a spool but It's 95% street car. I would however like to maybe run a set of stickier tires at the track some time and don't want to worry about it coming apart....
The trans is an 18 spline hemi 4 speed with cryo treated internals from liberty. I know it's probably still the weak link but I think it should be ok as long as I'm not launching it at the track every weekend with slicks.
