spacers might make it worse...........what is your rim size?
17x7, 17x7.5 18x7, 18x 7.5???
What size tires are you using? Is the rear rubbing or front too?
How low ar eyou dropped?
On the rear as someone suggested, shave those rear tabs, in the front you could cut the splash gaurd --- thats what someone else did on this board.............
Honestly a +40 offset is a

a +42 offset is pushing it
a + 45 offset and greater is good.........
also depends on tire size and how low you are dropped and how stiff your suspension is
