Type-approved without them?
That is my thought too. At some point I also read that the BRBs have to have so-called predetermined breaking points so that they cannot cause any injuries in the event of an impact. My 4/4 was fitted with BRBs by the dealer when I bought it. So I hope after 7 happy years that they have done everything right. I didn't know that you have to pay attention to the deflected weight but it seems logical to me after reading.
