I understand that not everyone will agree with my suggestions. And I'm good with that.
But let's take a look at some other things here;
Replacement rotors are marketed by a variety of companies. But before we claim one to be better than another keep in mind that nearly all of these are imports from China, and many of them are reboxed from the same supplier under different brands. Centric being one of the largest I know of their parts come in a half dozen different "label" boxes/brands.
Taking that to the next level a lot of companies are selling special rotors with slots, holes or whatever in them. Meaning they are simply buying the least expensive part they can and prettying it up for you- slotting, plating and putting it in a techno looking box. The shear scope of it should nix any thoughts that anyone selling on ebay is certainly not making their own rotors! Even on the bigger scale the thought that there are dozens of foundries cranking out rotors for hundreds or thousands of vehicles is a bit unrealistic. I probably get one or two request a month to have my own needs cast by a Chinese company if I want to contact their company.
As for pads...there are quite a few pad suppliers and options. (a bit less grand scale operation compared to casting rotors!) I've been doing this for 22yrs now and other than carbon or Ti rotors I've never heard anyone suggest you cannot mix certain pads and rotors. That flys in the face of how a rotor functions- pad transfer being applied, pad material liking pad material etc. I've never seen an iron rotor that won't work with a specific pad- unless that pad was specific to things like Ti or Carbon. What I have seen however....is that some pad material is not compatible with other pad material. Once pad transfer is in place replacing that pad with an alternate compound can be dicey. For that very reason many suggest you replace both pads and rotor, or at least turn the disc before you fit new pads.
From personal experience running PFC pads (a high carbon pad) and then replacing it with another brand was simply not going to work. The transfer layer of pfc compound embedded in the iron created a ice-like surface that the other pad had no love for. There was nothing wrong with the other pad it just didn't have an attraction to the pfc material. The point being; if you swap pads only be certain the new pad is the same or will function with the older material. There is no need for replacing or cutting under such condition btw. Nor have I ever seen a need for brand specific pads to a specific rotor.
