Ever since I got my (used) D5 over a year ago, I've been thinking about upgrading to 18-in wheels and wondering whether Defender take-offs would work. No hurry becuase I had a good set 5 Falken Wildpeaks on 20s. I had searched a couple times in the past about whether the Defender 18-in steelies would fit and couldn't find anybody who had done so.
Well, a good deal popped up, and I can confirm that they fit on my 2017 HSE.

 

Nice!

 

I like those!!!

 

Those look pretty sharp. *Way* too white for my blue D5 though.

 

Update. I replaced rotors and pads all around and the rims rubbed against the calipers after I put in the new pads. After a little grinding, all fine.
