I too have just bought a second hand deflector, must be something in the air
BMW original and would appreciate some help please.
I have the central deflector (part 1) and am about to buy the deflector holders and torx bolts (Parts 3,4 and 5) https://www.ebay.co.uk/itm/BMW-Genu...205419&hash=item2a53b39010:g:YLYAAOSwXAJYWARD
The instructions don't seem very clear on fitting the side brackets for the deflector to slide into, they just say secure the brackets with 20mm torx bolts. Does anyone know if there is a template or measurement, and do I need to pre drill holes? It just seems a bit flimsey if the bolts only go into the siver surrounds (as pic below) I would have thought that they screwed into the metal which I assume is encased by the plastic front and rear surrounds..
Guidance would be appreciated please, I have tried to work it out by looking on forum and web, but can't see a clear answer.
Thanks in advance
Clive
