Considering these for my winter set, I have a set of practically new Dunlop Winter Sport's that I had on my BMW for 2 years that have loads of tread that I fancy re-fitting on some rims for my new R. Not that it's bad in the colder weather but my wife is a nurse and has to go out in all sorts of weather and figured this would make make the car even better in the cold.
Found these on tyreleader for £95 each delivered which seems too good to be true, but a google around seems to suggest they are legit. The offset could be doing with a few more MM, but since I'll need to buy bolts for them with a tapered seat I can look at spacers with longer bolts at the same time if i fancy it.

They are double the cost here for example: https://www.performancealloys.com/borbet-y-matt-titan
Found a YouTube video that showed them - they look good IMO
