Ah, the old illegal Xrox bar thing has raised its head again. Personally I agree, but I can see that Xrox did manage to scrape in a compliance under the ADRs. That one you'll need to get their tech people to give you compliance details.
No mudflaps is asking for trouble. Make sure that the new ones are wider than your tyres. I have extended mine using the same plastic sheet that is used on rally cars. Tough as nails and has lasted for some 7 years now.
We used to fit aftermarket flares to a variety of 4WDs in the shop. Gave it up as a bad joke because none of them have any kind of decent mounting and they'd just come back, half off, for warranty.
