The euro r lip wont affect the washers will it, the washers are above that. Don't you just remove your factory lip and replace it with the the euro r lip which has the slits next the the fog lights.

I believe thats the only thing thats different between the euro r and standard euro lip. Our lip has a plastic bit next to the foglights, while the euro r has those slits as a part of the actual lip.

That's the impression that i got when i saw a picture of the lip taken off a euro sports. Correct me if i'm wrong but.
