Here is what I use for accurate measurements :

And, thanks for asking
here are the measurements I am interested in :
Rotor thickness (contact surface)
Overall rotor height
Rotor mounting surface thickness
Total caliper width
Distance from mounting points to center of disc
And finally from your Enkei 16X8 +38 wheels :
Distance from the mounting surface to deepest portion of the wheel (to evaluate caliper clearence)
Gap between inside wheel lip and front strut (which strut do you have?, as this has an influence on the result)
If you can include a couple of pictures of the caliper and disc installed without wheel to show how it fits from different angles, that would be great.
Thank you very much to take the time to sharing this information with the community
