They're pretty common. They work, can be difficult to get them to hold a position long term.

 

One of the genesis coupe trims came with them in the glovebox. I hate those things, but they work. Not sure why you would only put them on the front? I need some for the rear of my XD. The lowering makes it rip up the inside of the rear tires. Need to dial that out some.. assuming ill ever get it back on the road.
