Make those wheel well liners fit at what cost?

Just had new wheels and tires installed on 2018 crewmax, not taller than stock just an inch wider wheel with a zero offset, I was determined to not have to do any trimming or alter suspension, shop guy assured me all would fit... when I picked up my truck he had removed wheel well liners cuz of slight rub in reverse at full lock, need to get em back in since it looks weird and will probably do damage up in there eventually, shop owner offered to install just a little 1/2” strut spacer and that would do the trick, do you guys think that minor height change up front will affect long term wear/ lifespan of suspension components? Thanks in advance!!!! Have weighed the others options (heat, massage, trim liners etc.... 2018 truck seems trickier!!
