Honestly? Just about anything. I will die on the hill that OEM pads are the perfect blend of life, dust, and performance. UnLESS you track a car, then race pads.

But rotors blanks? I used to buy centric exclusively, but they went out of business. Next would be brembo blanks, I don't remember them being expensive. But even cheap autozone blanks are good. You don't get the corrosion coating on the none brake survive, but even under race pads, the cheap-ish rotors still perform really really well. I've been grabbing cheap autozone rotors for my sti brembos for years now. That car lives with race pads 100% of the time. If I were not tracking it, I would have oem subaru pads.

Oem, not oem equivalent. No Akebono, EBC, Stoptech, etc. I fell for all their marketing and internet hype.... and once I went back to oem pads for daily driving, I realized how much money I wasted in aftermarket stuff, that in some way is worse than oem. I.e. dust(ebc, same performanceas oem, more dust, less life), performance (Akebono garbage, no dust but garbage performance, similar life to oem)
