They are more affordable than anywhere else. If you need to replace a full set of these grommets this is the right place to get them. Your local car dealer will probably charge at least double that. If you go for all-chrome models, you'll be spending about three or four times as much. The chrome ones are a waste of time because the only difference is the underside of the lip where the threads are and you can't even see that part when the lugs are on the wheel. So what's the point? You definitely can't tell them apart in the car, that's for sure, last time it took twice as long!
