Cant really bash them. It is what it is. As long as the owner just is up and up with/about it, no problems really. At least not in my opinion.
If the quality is good enough for the street and light track usage, then all the more power to these owners.
For replicas, they do look pretty good though.
Now just don't go sticking on "Volk" stickers on these and all.
To the OP....cool set. For the cost....I would agree with you. Cant really go wrong, plus you said it as it was...replicas from the get go. I can respect that.
