I have those wheels on my car, and I just went through the kit I have set aside to make a replica of it and you are correct, the kit parts don't provide a front and rear as they should. I could have sworn they did it right. What a bummer, now I will have to machine more parts... In 1:1 it is enough to see, and being "backward" to me it kind of jumps out.
I'll say it again, you did a super clean job on that one, like usual...
