5 lug conversion 02' ep3

Hey guys I know there are plenty of threads about the 5 lug conversion out there but none of them really answer my question, I got my 02' ep3 couple months ago and notice it has the 5 hole conversion, now I need rear rotors but I wanna change all 4 the thing is that I'm not sure what conversion the previous owner did if it was from an rsx type s ,base or from an ep3 04-05, I read that there is couple differences but not sure if there's any when it comes to the rottors sizewise, so my question is do I buy rotors for an ep3 04-05, or rsx base or rsx type s 02-04?

Thank you guys in advance
ps. Let me know if pictures are needed I can probably take some.

OK first of all, all the rear brakes are the same so rotors for any of those cars will be the same. Secondly, RSX base and 04-05 EP3 have the same front brakes so you just need to determine if the fronts are Type-S brakes or not

Measure the front rotors. Base RSX/EP3 should be 10.3"ish and S Type will be just over 11.8". Or in that neighborhood.
