Von Ryan Racing will enter a second McLaren 650S GT3 in the 2015 Avon Tyres British GT Championship alongside the McLaren GT Young Driver car.
Euan Hankey and Salih Yoluc will also contest the full season in a 2015 spec car.
Hankey arrives with race winning form in one-make Porsches and Formula BMW on his cv, and will line-up with Turkish team-mate Yoluc who makes his debut in the GT3 category after a promising debut season in 2014.
The pair recently formed part of the Optimum team that won the GT4 class in the 2015 Dubai 24 Hours in a Ginetta G55.
