The closest thing we've found with regards to the splitter is the Ragnotti item (it has the correct part number on it) from ORECA in France if you're feeling brave with regards to the import duty lottery or alternatively Kam Racing stock them. Centre Caps were still available from RPD last time I looked.I plan to use it on a few sunny weekends and a couple of track days each year, otherwise it will be tucked away in the garage.
For now, I'll just make a stack of serviceable items that I need.
Apart from that I also need to find another front splitter as its already fallen off, new centre caps for the alloys and a few other broken bits that need fixing.
Haha, indeed.... on back order...
