The rear tyre mudguard is a must IMO - it was the very first mod I did to my M3W
Otherwise the whole of the rear undertray area will be smothered in road spoil - or whatever you drive over/through!
I did think the Factory had one now as an option?
Or is it still in development?
There are various posts on here showing how I and others did the mod.
