@ QUiKSR20 and Everyone

I got a pair of OEM adapters from stock speakers I bought. I am now planning to alter them for this R4 project. How much should I shave off the adapter rings for the proper spacing on the R4 to the e90 door? Just enought to avoid it from hitting the rear face of the grilles and being able to be mounted without hitting doors? The figures abve are a bit confusing. Maybe someone has exact measurements on how much to shave off? I will stick them up together with epoxy.

Thank you guys!
