Returning for an epic second series, expert mechanics Shane and Dan take supercars and engineer them to the max!

This series will see Maseratis going 200 mile an hour in Le Mans, an Audi R8 enter the Gymkhana Grid, and a Porsche turned into an ice-rally roadster. Alongside there will be Bentleys in the desert, Jaguars racing Spitfires and even an off-roading transporter carrying a Lamborghini.
