I have the pleasure of helping lots of customers who progress on from caterham racing. In this instance the driver I am helping is learning his way around the Aston Martin Vantage GT4 prior to the British GT event in 2021. 

Using old tyres I'm providing a reference lap for a customer at Oulton Park and achieve a 1:43.49. 

Sorry the throttle trace appears to incorrect on the video.
