HP2 Conversion

Hi,

my conversion preparations are slowly going into the last round. Since I feel little need to find out during the conversion that what does not fit or is missing:

So I have wheel bearing housings, saddles and discs/stones from s4. Wheel hub of the D11 continues to be used

Questions:

Before installation logo still new wheel bearings in - here I assume that it should be the originals of S4?

The brake disc covers I did not get from the S4 (in case of doubt not yet ). Do I need these mandatory or do I fit those of the UFO system (don't think about it - just ask for safety again :P) ?

The wear indicator contacts (original cables) are simply "cobbled together" or can one use the locking contacts of the HP2 stones?

Thank you for an answer

Sascha
