Has anyone ever ordered anything from JDM Hub (www.jdmhub.net), or had any experience with them?? I placed an order several weeks ago, and have not seem or heard anything from them. I cannot get in touch with anyone either through voicemail, or email. I am now wondering if they are a real company or what.

It's jdmhub.com, not .net. I don't know anything else about hem.

Go to the Carbotech website. I trust them with my life. Their first page says to not trust JD HUB.
I have no actual experience with them but I do have a lot of experience with Carbotech and they have been great.
