Under the Halfords Racing with Cataclean name, Shedden and Rowbottom will spearhead the team’s charge in 2022 while driving the Honda Civic Type R.
Rowbottom finished ninth in the final standings last year with one victory to his name at Oulton Park.
Shedden returned to the championship for the first time since 2017, securing a top-six finish in the championship with back-to-back wins at Donington Park.
Speaking of the news, Rowbottom said: “I’m over the moon to be back for a second season with Cataclean and Team Dynamics. I’d said to the guys from the outset ‘give me a strong car and I’ll prove to you I can drive’ and I certainly proved all my sceptics wrong last season and showed everyone that I can truly race.
“This year has got to be maximum focus for me to win the outright Drivers’ Championship, that is my goal and that is what I’ll be aiming for!”
Shedden added: “This is mega for me. I set my sights on winning the Championship last year, but lady luck just wasn’t on my side – we had a great car, but just couldn’t capitalise on it. I’ll be all guns blazing this year to get that elusive and record-equalling fourth title!
“The boys have been working their socks off during the off-season to give us cars that will be super competitive, so we both need to go out there now and repay their hard work. I cannot wait to get back in the car again, it seems like a long time ago we were last racing.”
The new BTCC season kicks off on April 23-24 at Donington Park.
