You suggest this even though he told us previously the LR tire was in more then the manufacture recommended as a minimum?
"I went ahead and pulled the LR out last night to the MIN suggested spec from Prowler, moved it a total of 5/8"."
just yada yada and proly more useless yada below because the response got me thinking about it. no argument intended, just offering what it made me think about which probably ain't right anyway.
IMHO the position of the tire in or out has nothing at all to do with the effects to rotation caused by stagger. The ONLY thing which effects how stagger will work, unless your traveling in a perfect circle is the loading of each rear tire and the direction forces act on the tire. Moving the axle out effected tire loading and because it slightly lowered the LR corner of the kart it effected the direction forces acted laterally to pull the LR tire to the right. The key IMHO is did moving the LR out cause an increase or decrease in the amount of slip at the LR.
Well you're wrong paul, its easy to prove drawing a line from the top of the right tire to the top of the left, then move the left tire out and draw the same line you see the angle of that line has changed where they intersect.
Moving the tire in increase the effect, and out lessens it
It didnt lower the left rear, it moved the left rear farther out from VCG which slowed weight transfer from and to the LR
