Some before and after pics..

No it’s not a direct fit. The RS4’s fenders are wider then a US spec A4/S4 so allot of trimming heating up and molding took place to get the thing to fit right… And not to mention having to offset the bumper shocks.

Your thinking of a S4 bumper. The RS4 is a Euro spec bumper, they do not come with the recess plate… No need to in the european market.
