The wings west sides are too "warped" to look good with the clean cut kaminari bumpers imho.
What I would do, is get the kaminari front, rod millen sides, and a blitz rear.
The straight angels of the rmm sides would meet up nicely with the kam front. And the blitz rear will complement the clean cut rmm sides, and also match the "air Intakes
" the rmm has with the shape that's on the lower sides on the blitz bumper.
But if you're really set on kam front and rear, I'd get kam sides aswell. They look real good. If you want to pieces of kam and a third whatever, then I'd drop the kam rear (I don't like it) and have kam front+sides with a different rear bumper.
