B11 Brake Rotor Question: CL18B and AD20V Assemblies

Consulting the FSM for front brake rotor replacement, I've found that there are two variants of brake assemblies: CL18B and AD20V. The manual does not state the difference between the two. My first guess is that one for the CV17 engine and one for the E16 engine. Does anyone here know the difference between the two variants? Also, are these just two different caliper assemblies and use the same rotor and pads?

CL18B brakes are for the E16 B11s and have solid rotors.

AD20V are for the heavier engined CD17 B11s. They have vented rotors with larger pads and calipers.

Thank you.

I specified the E16 when the rotors were ordered. I can go take the rotors out of the box and check.
