DEX410 handling

[qwkpony]

I recently installed the Tresrey front hubs and with the optional spacers they have available you can space the hub further up the kingpin (theres actually 3 settings available with these spacers... all the way down like stock, in the middle or all the way up). I'm trying to understand how this has an effect on handling. I assume it has some effect on caster (but static caster is not changed) or does it only have an effect on front ride height? Anybody care to explain?

Also, would someone care to explain what effect different weight diff fluids have on handling?
