i know that the rotor size is the same as 90-00 Integra (10.3')

Does this mean that I should buy integra rotors to replace my 91 civic ex brake rotors? Same go for pads?

 

yes

 

Rotors are the same, but the pads are slightly different between 90-93 and 94-up. I made the mistake of buying 90-93 pads when I used 94-up calipers. Just wanted to add this for future searches and as a general FYI.

 

so, I assume the 90-91 Civic Ex caliper and pad are the same as the 90-93 integra caliper and pad.

can anyone confirm this?

 

They should be the same but I would match the pads to the caliper they will go with.
