Rear pads/rotors 03 WRX sedan. Not tracked, only aggressive spouse driving ;-) Under$100 suggestions?
Centric blank rotors & their Posi Quiet pads are a good option imo. Or Power Stop. I've liked both from RockAuto.
If you're brave enough to venture to Minneapolis there is a great place called discount brake and equipment warehouse that has good stuff for cheap and people at the counters who actually know what they're talking about. https://brakeandequipment.com/
