Those are the lug nuts supplied by Volk USA for the last 3 years, there are no "Volk" specific lug nuts except for the GT-C ones. We do offer lightweight Rays lug nuts but they start at around $180/set.
We have two separate batches of Muteki lug nuts, the ones supplied as general Muteki lug nuts are "Made in Taiwan", the set you received to replace the Volk lug nuts should have been "Made in Japan", as long as the packaging on your lug nuts shows Japanese made you received the correct lug nuts. Please confirm.
If for ANY reason you are not satisfied with the lug nuts , we have almost 100 styles of lug nuts at MVP that we stock and distribute ranging anywhere from $50 - $300 in all different forms of materials, I would be happy to exchange the lug nuts you received with a waived restocking fee.
On a separate side note, the price on our website is outdated and is in queue to be fixed soon, you purchased the lug nuts around $20 less than they are supposed to go for but we processed your order regardless due to the inconvenience of the discontinued hat.
Thanks and I'm sorry for any confusion, when we update the price on our website we will be sure to clarify that the actual lug nuts supplied are Japanese Muteki.
Regards,
Kevin
