"Installation of new brake pads is approved only provided that the brake disc thickness exceeds the specified dimension (see table).

Brake discs must be replaced when they reach the nominal thickness (see table) minus 2.4 mm!"

Nominal size (diameter x thickness) mm 340x30
Minimum brake disc thickness stamped on brake disc chamber mm 28,4

Yes you need to measure at 3 spots and even even on a few different position on the disc...

I got this for $25 https://www.harborfreight.com/6-in-l...per-63714.html
Thanks for the link to the caliper. They've got one in stock locally to me. I'll pick that up before I replace my pads. I've only got 35K on my original pads and rotors, but I'm going to replace the pads w/ Brembo ceramic. I wanted to check the rotor thickness, but didn't want to spend $$$ on a tool I won't use often.
$27 is perfect.
Check the EBC red stuff if you don't want dust.
Else EBC yellow stuff are my choice for sport street and even moderate track
