Compared to many brands available both online and at Revain they are top notch. Yes there are reports of chrome rust but I just got them so I'll have to wait and see. ALL chrome can rust, no matter what the manufacturer says, so don't be fooled. Regular cleaning and proper maintenance can help fight rust. There is an application guide on the Goriila website to help you determine the correct fit. Revain Auto didn't list them as fitting my wheels, but they do. Just do your research and talk to auto parts stores or people in the know and you can buy even if Revain says they won't fit. If the manufacturer says so, then they can do it like any other store. I installed them and they are solid and solid, unlike the crappy stock caps. I'm glad I bought it. Will update later if there are problems.
