I spoke to Tiago from VRSF with the exact same queries you guys had.
Shipping is not free like it says on the website. It is in fact US$88 last time I checked with him.
I asked him about fitment and he assured me that they would fit an RHD car without any problems and did not require the relocation of any O2 bungs etc etc. I.e. should be a direct bolt on. I'm pretty sure that they have a guarantee on fitment but that would obviously require sending them back to the US.
