What is adjustable on the stock suspension.....camber...caster...toe?

 

They all "adjustable".. Toe is adjustable through the tie-rods.

Camber - You'd have to bore out the strut to knuckle hole.

Caster - You'd have to bore out the hole where the strut mount attaches under the hood.

I'd say you don't want to mess with caster, there is really no reason to on stock suspension.

Someone correct me if I am wrong.

 

Without mods? Front toe. That is it. That's all a typical alignment shop will do.
