Dylan

Dylan and Sebastian Guest, identical twin brothers, collaborate within their family-run race team GB Evolution, also known as “The Guesty Boys” working together to build their future. Together they build and fine tune their karts, actively engaging in the mechanics of their own karts. Their track experience is leveraged to optimise their karts for peak performance and to obtain the best lap times and position.
