I sent them an email also and got a response 1 week later. The disc brake conversion is if I remember correctly 2500Euro ($3,322USD) and comes with a Toyota bolt pattern. Of course that did not include shipping from Germany. I sent them a reply asking if the Toyota bolt circle was the only option and have not received a response. This kit is not offered on their web site from what I could see. The OMT web site is still up. I called the former owner, that's how I found out of the sale of the business.
