you might have them over-rotated toward the front of the car? What brand are you using? I used AMD and the were a decent fit.
On the trunk side flange that meets the flat/upper portion of the trunk over the axle, does the new wheelhouse match up well? there is a flat edge on the wheelhouse that should match up with the flat portion of the trunk. I used that as a guide to tell me if they were over-rotated or not. There is alot of movement in there, you might have to add a filler patch between the trunk and the wheelhouse if you cannot get rid of it. Or possibly get an AMD wheelhouse?
