I sent Kevin Adler an email from the ultra4racing.com link, and his Facebook page, neither have been acknowledged as of yet. Team Chaos racing runs them on Justin Hall's old buggy and they worked well when we competed at werock here in Texas. They said he can be hard to get a hold of, and may have met his capacity for sponsorship this year. I would love to try a set, and will definitely let everyone know how they work if I ever get them.
