Okay, so I needed new rear rotors for my Kia Sorento and nearly had a heart attack seeing the $150/each price tag at auto stores. Found these ACDelco Silver ones for way less and took the gamble.

Installation was smooth—paired them with ACDelco ceramic pads (B07CJ9KGSQ) and everything clicked together. Braking feels solid, no weird noises. BUT... the rust. Oh boy, the rust. These things oxidize faster than an apple slice left out on the counter. My factory rotors had minor rust, but these? Full-on 'abandoned shipwreck' vibes.

Update: I got fed up and hit them with a wire wheel + high-heat Rustoleum (weirdly dried gray, not black). Now they look decent-ish. Performance-wise? Zero complaints—just don’t expect them to stay shiny.

TL;DR: Great fit, great price, stops well. If you’re cool with DIY rust management or just DGAF about aesthetics, these are a steal.
