While washing my brand new S2000 for the first time, I noticed that both rear side panels behind the rear wheels are loose and move in and out loosely about the pozi screws holding them that are in the rear of the wheel arch. QUESTION: is this normal or are the screws loose, they don't feel loose.

 

The plastic fasteners at the rear of the wheel well arch have been broken on mine and so the panels are loose. I think it happens with an impact to the rear bumper.

 

Take it to the dealer and have it fixed.

 

Mine is loose too (driver's side). No impact to rear bumper, but I did spin out @ 1 year ago, and my driver's side rear tire hit the curb pretty hard...

 

Mines loose on one side. The clip is gone. I replaced it once. It fell off again. I don't think it will fall off, so I've left it alone.
