they will fit but will stick out from the guards more giving it a phat look, the less the offset is the further out from the centre they will sit..... my rs8s' wantanabes were the some offset as bensDR30 mentioned but 7" at tne front and 7.5" at the rear, the 17" P1's i've got now are 8" at the rear with an offset of 22, just fit no scraping....
