Thanks guys.
Was a fun day.
The GTR was the quickest thing I've ever seen in a straight line on track (would of left the atom's for dead) and tbh wasn't slow in the corners.
I've got a few videos from Abingdon the week after this which I'll have to post up.
Below is a video from my mates R400. We went out together at the end of the day. I come past later in the Video http://youtu.be/Pg5TcIGzEKo
