Why do a 5-lug conversion...

I think one thing forgotten here is that with the 5 lug conversion the braking and overall handling is a 150% improvement. You couldn't pay me to go back to a 4 lug setup simply cause the improvement in handling!!!

how does 1 more lug nut provide more handling besides maybe better braking

The additional single lug does nothing for handling or braking. It is the required SN95 spindles with better ackerman steering built into them that improves the handling.
