i'm an old racecar guy , but ; when it comes down to caster & camber it's all about how much tire tread is on the track(camber) said easily,when going through a corner you want as much tire surface on the track as possible; so for a road coarse you probably want 50/50.(caster) is usually driver preference,especially with power steering by armstong.lol.
I DONT KNOW IF ANYBODY EVER TRIED TIRE TEMPS ,BUT IT'S THE BEST WAY TO KNOW WHAT YOUR CHASISSE/MOWCHINE IS DOING.BY CHECKING TIRE TEMPS ,YOU CAN GET AN AVERGE TEMP;BY CHECKING OUTSIDE ,MIDDLE ,AND INSIDE OF A TIRE AND YOU WILL KNOW IF IT'S ON THE GROUND/TRACK .THE CLOSER YOU GET YOUR TIRE TEMPS THE BETTER,TIRE TEMPS ARE TAKEN WITH A PYROMETER.
