Wouldn't say I have more experience but I used the original donuts for the inner as they were in great shape. I did see in an article than some people gave them a good dose of copper grease (I didn't bother) but getting everything back together was damn tight. I just bought some longer bolts M10 (allen head, M10's with a hex head will be too big) then nipped everything together, tightening all four bolts gradually in rotation, you'll never manage it with the original bolts.
*Admins* could we move part of this thread to technical as the Groupbuy is now complete and this part of the thread could be useful for people fitting adjustable springplates.
