Rubbing issues with ’14 800 S after 1K wheel swap…

Title is pretty self explanatory…

After doing a wheel swap on my 800 S for some 1K take-off wheels (and 1-inch spacers), I noticed the rear fenders have some rubbing damage on them. Not a big deal, and I understand that I went from a 26 to 29 inch tire, I was just wondering what the remedy it to fix it and avoid further damage; a lift kit, preload adjust or dampening setting adjustment or a combination…?

Thanks in advance for thoughtful/helpful replies!
