From what I could find the RH154 kit is a 17" wheel so it might not fit over the front brakes on an M, but I didn't even look at the PCD or offset to be fair!
Before a road trip in 2021 I bought a single front 224 wheel on here for £60 and got a new tyre fitted to avoid a "show-stopper".
It might take up most of the boot space but I know it will do the job without any limit on distance and speed, which would be handy when I'm 400 miles or so from home. And if you use a space-saver you still need to get a full size wheel in the boot anyway!
