So, fitted the splitters tonight. Pretty straight forward. About an 80% perfect fit with a bit of misalignment at the end towards the wheel arch but reckon I can get them 99% right with some fiddling, however, it was getting dark so I called it a night. I sourced them from Aliexpress and they arrived in a week for $180 delivered:
