Camber adjust plates!
Or live with it I guess, used to have the same on my MK1 Micra with a 40mm drop. Cornered like a go cart but always wore the inside shoulders no matter what I did. I used to feed it second hand tyres from the classified in the local paper/gumtree, anywhere I could inspect them first! At a tenner a pair I really didn't mind how long they lasted
Or you could do some more mods on the suspension like camber plates, or you might get lucky with the tracking... Depends how low you've gone and whether the rears are also wearing.
