well i need to replace my rear rotors, so i was going to do all 4. on ECS website i see the rotor size 245mmX10mm. I am assuming the 10mm is the rotor thickness? the reason i ask is because there are 2 versions... 245X10 and 245X12. does it matter?

second question is related to pads. has anyone ever used the ebc green pad?

thanks
