We’re the knockoffs using 3M adhesive though?The performance plus is molded on the ends to hug the rear hatch area better. I think it is going to stick a lot better. I’ve tried some knock offs and I can’t get them to stay down. I switched from the Razzo to this one, and used the savings to buy the matte carbon mirror caps. I think it will be a nice touch. Just have to have my PPF guy wrap the matte mirror caps in XPEL Stealth to protect them.
