United Autosports has finalised plans to run two cars in the British Touring Car Championship next season, for James Cole and Glynn Geddie.
The GT squad, which narrowly missed out on the British GT title this year, tested an ex-Frank Wrathall Toyota Avensis last month.
It has now been granted two licences under the BTCC's new regulations and will run Toyotas for Cole, who contested half of the 2013 season with Team Hard, and GT racer Geddie.
Team owner Zak Brown said: "The BTCC is the most popular motor racing series in Great Britain outside of Formula 1.
"It's seriously competitive, the racing is exciting and it's commercially viable, as the capacity grids show. I'm thrilled that United Autosports are going to be part of the BTCC."
Co-owner and former racer Richard Dean added: "It's a new direction for the team and we have a strong driver line up in James and Glynn.
"James's BTCC experience and Glynn's pure driving skill will be invaluable to the team in 2014."
UA has already confirmed it will remain in British GT, running an Audi R8 for Matt Bell and Mark Patterson.
