If I'm mistaken, please correct me if I'm wrong, but I could of sworn I read an article/blog that mentioned when the person visited Todoroki's shop they were told the fenders were produced by TRA-Kyoto but the overall design influence for these fenders came from Dream Projects themselves. So judging from that unconfirmed rumor there might be that indication of FRP quality and fitment for some people.
EDIT: Found the link. Credit goes to the Midnight Roulette blog. You can also get an idea of how the front and rear look/work together from different angles. Click the link for more pics.
