British Touring Car race winner Dave Newsham will drive AmD's Ford Focus in the series next year.
Newsham won two races for ES Racing in 2012 and finished 10th in the standings this year in a Speedworks Motorsport Toyota Avensis.
AmD recently announced it will run an ex-Motorbase NGTC Focus in 2014 and has now confirmed Newsham.
"I wish Speedworks well for the future and I can hardly wait to get started with my new team AmD," said Newsham.
"[AmD boss] Shaun Hollamby is a former BTCC driver so he knows exactly what it is like to be in my shoes.
"I respect him highly, and he runs a very professional operation with very experienced personnel, some of whom I have worked with before.
"The Focus is very developed, and was seen regularly on the podium towards the end of the 2013 season. So in essence, the whole package should be a marriage made in heaven."
Hollamby added: "The level of competition means that every element of the team has to be at a very high level to succeed and Dave has shown race winning speed and race craft since entering the BTCC.
"AmD is looking forward to providing him with the tools to be a regular podium contender."
