Croft was a new circuit for Jacob, but he was on the pace straight away at last week's official Porsche test day, finishing the first session second and ending the day second in class and eighth overall.
“Croft is a lot of fun! It has some fast sections that need confidence and experience, but we learnt quickly and were on the pace almost straight away.
“It's early to start thinking about the championship, but it will be won or lost on consistency, so that needs to be the focus from now until Brands Hatch at the end of the year.”
All three races are live on ITV.
