How to improove oem WHEEL ALIGNMENT settings (toe&caster

[Apolan]

Lets talk about this. I'm wondering if oem alignment can be adjusted to perform better (fast street use). I will be running just sporty lowering springs and sporty shocks. Cca 40mm lowering (no coilovers).

caster: 3°40'
toe: 1mm toe in after 180° advance of the wheels

Probably best to leave toe oem for street, as we dont want to torture our tires too much. But how about caster setting? 3°40' doesn't seem alot, so how much can be gained by increasing the caster?

PS: how about TIRE PRESSURE? the manual says OEM inflatation should be 1.7 bar (24 psi). What combinations have you tried and experience?
