Well...quality costs...That's not that bad.

I will measure all my sleeves. I did not check the z8 to see if they are the same. I will have to see how much material it is going to take. The long ones will take longer to make. but at least this part of the project should be quick to do.

Do you have the yellow bushing like the one we have here in Quebec on our Z ? Mine is a 53" 2015 with wheels spacer.
I have Check mine today and i have absolutely 0 play anywhere .
All is tight like new. ?? I just put lithium grease every 500km.

Mine were gray. They call for the same part numbers. Maybe they did update them, but not the part number. I still think delrin is the way to go.
