How much traction? Some of us break loose on NHRA prepped dragstrips, not only off the line, but at the second gear shift as well.

But an LSD isn't going to help much with that anyway.

Last year the only significant mods I made over the previous year was rockers and LSD.
Both were good for .5 sec improvement in my quarter time. Some of that gain was in the 60 foot times.
Not all of that improvement was due to the rockers.

The Lsd will make a difference in your 60 foot times.

Hell, even lowly cars like mine have issues on NHRA/IHRA approved tracks. I'm not squaking on 1-2 shifts, but the torque curve on these cars starts out very high very early..

Very different from the Aurora I drove (Jim W'*....) But his was more fun on the freeway for sure. It wasn't quite as fast as my car off the line, but it very quickly makes it up.
