Few Suspension questions

[hellllo]

I can't find answers to my specific questions but here it goes. Note: I'm still learning about cars, so please don't flame. Quick history, my bro passed away and I'm left with his car. I don't know much but I'm learning.


I just noticed my driver side wheel sticks out more than the passenger. How can i adjust it so they are even? I've torqued down my lug nuts, and checked control arms. They look good.

I'm running alot of caster, I'm wondering how can it, to be running 0 degree caster.

I know how to adjust camber on the front suspension (camber plates), but how do i adjust camber in the rear, they don't have camber plates.

My bro's car has following suspension mods
Tein coilovers, tension rods, and rucas

Thanks for your patience
