I've done the drilled, slotted, cryo deal before without any luck as well. They look nice but think 90% are in the wrong application. I first went with AutoZone Gold High Carbon rotors for warranty and will copy n paste his info about then and Centric below. High carbon actually makes the rotor softer which was news to me.
Stoptech hoses are DOT certified and the rear set came with 4 hoses even though listings only said 2 at RockAuto
Part#'s are-
Centric Premium Coated Rotors-
120.66065, 120.66067
Stop Tech (Centric) Stainless hoses
Front-95066002
Rear-95066502

Most of the lower end white box stuff you see in Autozone / O-reilly / wherever are similar...we actually supply a lot of it to them. When you get into the "higher end" stuff at the chain stores, it gets interesting. A lot of it is simply the white box shit with some sort of lipstick (plating/coating/paint) and a shiny box with a bunch of marketing jargon. Often times the "higher end" program is simply sourced through a different vendor that for whatever reason has the illusion of being better, even though they're not much different. Just about all production rotors any more come out of China, but like anything, they will build to whatever price point you want. Our premium stuff is cast using a fines and mold, while the economy stuff uses cheaper coarse sand. We also have casting process specs concerning core box size, cooling, etc that are not in place in many of the factories. The "high carbon" was actually started by us, we developed an alloy that was considerably softer, like OE European stuff, to work with the Euro style abrasive friction material. High Carbon was what we branded that alloy, which had considerably more to it than the standard G3000 with a couple points more carbon in the mix. Everyone else jumped on the "high carbon" bandwagon, by simply adding a bit of carbon, but the rotors aren't functionally any different than the standardG3000 iron in testing.
I'd recommend Centric Premium rotors. Assuming this is a non-XL Denali, Part numbers for the front rotors are 120.66057, rear rotors are 120.66065
I would need to get a separate cheap (IF they exist...) grill first and do a practice run.
