I have tried many different setups of rotors, pads, OEM upgrades, off the shelf BBKs, custom BBKs, over several different cars I have owned over the years.
It really comes down to 3 things:
How you use your car? (track, auto-X, spirited street)
How much you are willing to spend?
Is brake noise acceptable or unacceptable?
My recommendation is to go with blanks, so they can be turned and have less noise, you can pay extra for a brand name (Brembo, Stoptech, DBA) rotors but that’s not necessary + ceramic (non-performance) pads, you can find it all on eBay for less money.
I would avoid; drilled non brand rotors and auto parts store generic brake fluid.
