James Thompson will return to the British Touring Car Championship from the next round at Thruxton in two weeks, replacing Gordon Shedden in a Team Dynamics Honda Civic.
The 2002 and 2004 champion last raced in the BTCC for SEAT during a part-time campaign in 2006 and has since raced in the world championship for N.Technology.
Following N.Technology's withdrawal from the WTCC, Thompson tested for Dynamics during the winter while searching for a full-time drive.
"James's addition to the team is one I have personally hoped for since Matt [Neal] moved to VX Racing at the end of 2007," said team boss Steve Neal.
"James is truly one of the world's top touring car drivers and I am absolutely confident that he can take the fight to the opposition and provide us with a further step-up in performance."
Dynamics hopes to add a third car later in the season to allow Shedden to return to the championship alongside Thompson and David Pinkney.
"This change in our driver line-up has come about due to contractual commitments," Neal added. "Gordon has been part of Dynamics since 2006 and has been a great performer for us.
"We are currently negotiating further sponsorship to run a third car for him which is hoped will materialise sooner rather than later."
