[UPZ SKI/DIN Adapter installation]

When installing, did you just screw in the screws that came in the box?

Yeah I am a bit worried about the forward flex, but I want to try it first.

[UPZ SKI/DIN Adapter installation]

Hello forum, 

I wasn't sure where to ask, so excuse me, if I asked on the wrong subforum.
I just bought the UPZ RC12 with the SKI/DIN adapter and I'm having problems installing the heel part.
The holes for the screws seem very small and I don't want to break the boot on the first day, that's why I'm asking here.
Are you supposed to just screw in the screws to make bigger holes?

Thanks in advance
