So been reading the 4907 Manual again ( I do this regularly to catch what may have been missed) and I caught something. The Caster info shows the front Wheels/Arms and explains the diff between 4,7,10 degree and the effect it has on steering etc.
I am curious about the rear Caster does it have the same kinda relation to Oversteer and Understeer that the front have?
I ask as I found my RPM arms apppear to be built with between 7-10 Id guess 8.5 degree Caster while I noticed my rear seems to have 4 degree.
Should I make the rear match the front( ie Higher caster to increase Oversteer/Reduce Understeer and Lower caster to reduce oversteer/increase understeer??)
I have major oversteer and do not know exactly why for sure unless it is to be expected.
