Picked up a 2019 Signature a few weeks back and replaced the wheels with RAYS Gram Lights 57Transcend. Specs are 19x8.5" 38mm offset, tires 245/50/19. Perfect flush with fenders but thinking about putting the Eibach pro kit springs on this spring to eliminate some of the gap.
Wheels look great! That gap could use some help though, like you mentioned.
