Hi Vind, and welcome to the forum from Scotland. Can't help you with your question as aftermarket parts available State-side are not available in Europe. I do like that grille though. You will get an answer to your question very quickly though on here. Lots of friendly people all ready to give you advice and help. Are you considering buying a 300? If so you have come to the right place for assistance.
Welcome to the forums, Vind! As to your question, I don't see any body kit on that particular SRT....some mods in the front, yes, but no kit. The grille looks like the ABS plated bright chrome from Grip tuning.
