I've got the exact same ones on my clubman fronted van, because they use the same screw holes as the standard (exposed screw) late model uk mini flares I had.
A little bit of trimming was involved, but they feel much better quality than the plastic ones.

I like them.
I also used the black rubber strip between the flare and the body as well as their anti kink chrome trim. I would definitely recommend both of these to be fitted when fitting these flares.
TIP: I cut the chrome strip so I had separate lengths for each of the flares and then one down the sill seam. IMO this looks heaps better than when the trim strip sits away from the flare/body on the transitions between the arches and body.
For the price I'd say go for it, especially if you have the same type of (cheap) flares I had. Also, as said, clubman specific flares are a bit harder to find.
PS: the fit is not perfect, (as you can see in that pic with the light visible) but I'm happy with how mine sit on the car.
