You can use a phone app to get a 360deg reading and put the phone against a ruler or straight edge on the rims , if you measure from top to bottom of the tyre it'll be a false reading due to sidewall flex at the bottom of tyre.
My mk2 didn't have any adjustments at all. .. it's how it worked out after lowering it , took it to alignment shop to get toe in corrected, that was it..
