I had plenty of people mistake mine for actual performance brakes. They weren't some Joe shmo either, they had modded performance vehicles of there own. I would always laugh and tell them they were just covers when asked about them. I did have power stop slotted rotors and upgraded pads tho. The covers were red with "Denali" on them. And no they didn't keep the brakes from cooling down enough to matter, they are made from thin, sturdy metal and only cover the outer part of the caliper and a small amount on top, not the entire caliper. I wasn't running hot laps on an auto cross track, strictly a daily driver. Are they a bit tacky? Some will argue they are (obviously ^), but that's all personal preference. This time around, I'll probably paint the stockers if even that cuz the covers are kinda pricey for what they are.
