Looking at the website where those pics are from you can buy from JPS?
I don't understand Japanese but the prices for that kit are on this link:

Also, if you go over to the US side of the forums, if you click the LOC network menu at the top of the screen and go to the US forums there are lots of members over there with these cars who might be able to help more, I don't there are really that many of these cars in the UK?
