Very good tune for a big heavy car. Nice to drive and quick at 550pp. It's a bit nose heavy which means that to get the car to point into the corner you need to turn in a lot earlier than normal. This is not a problem because once you get used to what you have to do the harder you drive the car the better it responds. You just have to be smooth and it will repay you. I though about moving the weight ballast around to help the turn in but I suspect that it would adversely affect the balance of the car and make it harder to drive.
Great job GR65 as always.
