What’s the difference of the two both advertised are rear spacer, sure look different. Hate to order the wrong one.
I'm not sure about the difference, but I ordered and installed the part number 150PR10. It fits well enough but I did not get the expected 10mm change in height on the drivers side. Not sure about the mechanics of that but others have reported the same thing. Maybe you need to adjust the front at the same time to get the desired effect, who knows...
