Can you elaborate further on the remaining 20%? In your opinion, what makes that 20% for this car to be difficult to attain, what factors may be difficult or risky to get to that level, and would some adjustments or modifications may help?

Thank you again.
I think what makes it hard to extract the last bit of performance is that the car is so good! It does the 80% so easily it almost lulls you into a false sense of security, making you think it is foolproof! However, it is ready to bite you back when you do overstep the mark. The problem is knowing exactly when you are on the edge of overstepping the mark. Also the other thing is the turbo. Even though the power delivery is very linear for a turbo, it is not linear, and you have to know exactly what is going to happen when you push the pedal.

A good analogy on what I mean that most of us would understand is a comparison between street tires and racing tires (eg type r or full slicks). Street tires lose grip progressively, squeal, and generally let the driver know what is going on. When they do let go it is predictable. Racing tires are quicker, and have more grip. However, the loss of grip and how they behave can take some getting used to, and they can unnerve some drivers.

Going from E92 to F82 is like making that progression in tires. The F82 is quicker, has more lateral grip and is a more race focussed product. You can definitely go faster. However, learning where the limit is and how the car will behave on the edge of the limit, how it puts the power down and how the throttle modulation works etc will take some seat time and confidence in the car.

Hope that makes sense
