I just ordered a set of Koni yellows to go with my TSW springs and they're on the way. I've read that there's about a 2mm requirement of drilling for installing the rears for the R56. Does anyone know if the 2011 R56 still requires this drilling? If so, do I need a special drill and drill bit? Also anyone have pics of what area i'll be drilling at so I can visualize the install prior to actually doing it this coming weekend? Also are there any other tips from anyone who's done this install or similar for a heads up other than the drilling tip? Thanks!

 

Nothing special, you just need to widen the hole, that is all.
