I'm getting ready to install Cogent DDCs in the 2015 and nowhere did I write down the diameter of the stock spring collars (spacers). I know the stock collar length is 150 mm but I need the OD to get some PVC pipe today.
Does anyone know offhand the OD of the collars?
Edit: I found the old piece of pipe I used to cut the necessary 160mm spacers for the 2012. It's 1" PVC. The diameter of the stock ones is 34 mm.
