So this has little to do with the other current 8.75" narrow rear end thread, but got me thinking.

I'm wondering, does a narrowed 8.75 give the center section a tougher time in high HP applications, in that the narrower the rear, the less "spring/twist" in the axles, and I have never heard this as a strength criteria mentioned when we have the monthly threads on the safe power range for an 8.75"?

So we should now include narrowness of the rear in the discussion regarding car weight, tire size/width/compound, gearing, application, back brace, billet caps, etc?
