Let me start by saying these ACDelco rotors saved me a ton of cash compared to auto parts store prices. For my Kia Sorento, they were a perfect fit right out of the box - no annoying modifications needed.

The installation was surprisingly smooth. I paired them with AC Delco ceramic pads (as recommended by another reviewer) and the combo works like a charm. Braking performance feels solid and consistent, even during sudden stops.

Now for the not-so-great part: rust shows up FAST. Within weeks, the non-contact areas looked like they'd been through a coastal winter. It's purely cosmetic (doesn't affect performance), but if you're particular about your car's undercarriage aesthetics, this will bug you.

Pro tip from personal experience: Hit them with high-heat Rustoleum paint before installation. I learned this after the fact and had to do the messy wire-wheel cleanup. The gray finish actually looks decent now!

For budget-conscious drivers who prioritize function over form, these deliver excellent value. Just know you're trading some corrosion resistance for those savings. They've held up well through daily commuting and several road trips in my case.
