Well I got my alignment done yesterday, they shim'd the rear left wheel's toe, and now it's perfect. This shop is the best in the area so I go on.

anyway, i got the final reading spec sheet. all specs are with very good to excellent range of factory except for one.

the caster is way off on the left front and the right is at the top most spec.

I was reading caster is not adjustable, what now. what should I do? I further read that this effect steering...???

Guru please

 

there should be no reason for the caster to be off. unless of course the front shocks have a right and left side . aka the shock isnt straight up and down but angled / more to the right or left of center.

 

Does anyone know if the Tein basic coilovers have a right and left

 

the struts and srings are interchangeable left and right. i dont think there is any caster adjustment. have you bumped any curbs aor anything that could tweak the suspension? also, you said they shimmed the toe adjustment. there are no shims, its just a tie rod lenght adjustment. hope they didnt charge you for shims.
