Optimal wheel base for RR (3Wheel)

[St_Louis_Racer]

Is there a preferred wheel base for RR's namely 3Wheel. Our car has the
the rears and fronts even with their respective ends. This longer wheel
base would take it longer to turn requiring more toe in. More toe causes
less potential for wiggle I've read. Just don't wanty to be missing the boat on something here.

Also, does anybody use a harderner around the axle holes ? I read this in a post:

do this = breakdown after a few runs
"Clear liquid nail and goop after drying for a few days seems to not do this, and some epoxies aswell. Gel super glue, sanded also has shown some decent results.
