Discovery Sport Mud Flaps

I have side steps on my Disco Sport 2017. Does anyone have experience of fitting front and rear mud flaps as well? I've looked at the YouTube clips but they're all on cars without the side steps fitted. Are the two compatible? And is there any real difference between the LR parts and the many available on e-Bay at a quarter of the price?

The LR flaps are betterer quality in general across all the vehicles they make. They will last longer. Never looked into fitting them on a DS. Are there any pic's in the sales brochures? Looks like there's different rear flaps for with/without spare wheel.
