Yeah I found that out. I returned the rotors and pads. I ordered the 2018 ILX front and rear Rotors and Pads. I have a 2018 Si and it has the same exact setup as the ILX.
I have these EBC rotors and pads. And I noticed that the rotor is slightly smaller than oem and the pad isn’t exact to oem. Would this still work on my 18 si?
