They appear to be very well made and fit the grommets. The problem I had was that the grommets have a different thread pattern than the factory ones. won't fit the holes for them (you shouldn't use them for this, but still.) and the bolts that come with the kit won't thread onto the factory bolts due to the different thread pattern. To do this job you need to buy bolts that match the factory wheel studs (6 per wheel, 4 wheels = 24 studs) and then buy wheel nuts that have their specific thread pattern to match the wheel studs of those spaces (same again - 6 per wheel, 4 wheels = 24 nuts) If you buy all of these nuts they will have no value.
