What clearance do you have???
As the pads wear the spacing will get better, I assume.
Also the caliber just touches the inside of the wheel pant. Do you think this will cause problems more than the obvious wear of both parts????
I was a Big Tire "Beta Tester" having installed 380's on my Rocket and later my RV4 back in 2008. I purchased them after reading Steve Sampson's construction blog of his masterpiece RV4, G-IKON.
Cleveland wheels have close tolerance as well and I installed washers to allow for clearance as you did. I trimmed my wheel pants accordingly to increase clearance. I didn't notice any speed loss.
You're going to like the change however, especially if you operate primarily on soft turf or grass. Operating my Rocket from my home strip at the time "The Swamp" was a quantum leap better in ground handling especially during rainy season in FL (all summer)
