Now, having experienced this before I knew it was probably going to do a small correction upwards.
So I held the brake on until the lights were about to change, having released the brake the rear lifted slightly and yes I did put the gas pedal to the metal for experimental purposes of course.
So as it countered the weight transfer, it gave it better traction off the line.
C YA Bye Bye GTI !
Another use for the clever suspension, thankyou Citroen.
