Car.ini and steering rod ratio

Hi, What is car.ini steering rod ratio all about? is it converting controller input to car input?

Also, Where is the SteringRatio values in the suspension dev app (pictured below) , I think it is the box that says [STR: ***]

If I turn my wheel 90 degrees should I see 90 in here?

Finally, what is KPI? I know caster and scrub angle, but I am not familiar with this one?

[
LINEAR_STEER_ROD_RATIO=0.00175 ; Because of AC complex suspension geometry, you need to calculate manually the steer rod ratio
; Enter AC in dev app mode enabled
; Open SUSPENSIONS app
; turn your steering wheel by 90 degrees
; check the actual steer ratio value
; modify LINEAR_STEER_ROD_RATIO value until ingame steer ratio and car.ini STEER_RATIO values are similar
