can you give us some handling-tips???
Not really, my experiences are too far removed from the power of the new car. However, from watching three wheeler racers, it is obvious that smooth is king. If you have to appear to correct for slides/spins etc you will be slow.
Very, very guardedly as I've no idea how it applies to the new car, but in a vintage one, if you are rounding a corner too tast and get understeer, you open the throttle a bit. This would have you in the hedge with most modern cars, but does definitely work on a vintage three wheeler - I was attacking a roundabout rather too exuberantly, approaching the curb and opening the throttle brought the back round a bit and problem solved.
