Wish my DT dealer (and their grease monkeys) would even acknowledge that a finger plate is needed. The clown spent more time arguing with me about it than it would take to just do the job! Sheesh - aren't these locations in sync with regards to training and equipment? I wish I could have them call a GOOD location for some how-to education...
A good technician really won't need the finger plates, the Toyota wheels will balance on the hub, but the finger plates make the process ideal in my experience. TBH, I just put on new Falkens, and road forced balanced without the adapter. No vibrations at all.
