I've used PowerSlot (slotted only) rotors on a 2003 4x4 Expedition & 1998 Honda Civic with great success and noticeable improvement. They were on the Expy for over 8 years when I sold it. In each case I mated them with a Hawk pad. I want to say I paid $100-$150 per pair of rotors and $60/pair of pads. I specifically didn't get rotors with holes due to $$ and they collect mud (for the Expy).
I bought the kit for my 2012 GC Laredo and I did see an improvement over stock. But you must follow the break-in steps to get the full benefit. Enjoy!!!
