A complete transmission mount (the 2 aluminium brackets) incl the dampening rubber costs less than $75 afaik, so if vibra technics is serious in marketing these parts in an adopted form, the investment in costs to line up their ideas to the original bmw parts is negligible. Running to the store and get them costs more if you consider an average hourly rate for an engineer.
So I don't see why they need a car per sé
