The diffusers from Germany arrived today. They were well packaged and undamaged. The quality of workmanship is excellent. The finish on the raw side is excellent and the thickness of the layup of the glass is more than adequate The exposed side is fine if you wish to leave them unpainted as the quality is there. They are very stiff and will definitely last for sure. As the OEM parts are. I will paint mine yellow to match the car so I will add pictures when primed and painted. Give me a few days. Overall quite happy and I am picky.
