After testing these cars yesterday after the release, and today doing some hotlaps and long runs with my friends, we got some conclusions about the handling. In general the cars feel fine, with the expected understeer at low speed. It takes three or four laps to warm up the tires to an opperational temp. So, don't change the setup before doing five or six laps. Braking before a turn must be gently, letting the engine slow down before downshift, other way the car will loss the line. You must release the throttle in the right moment to transfer weight to the front and get grip on the right moment. The corner exit isn't as easy as the size of the rear tires makes you think it will be. Then when you get the right lap and line and you start to push the car, and very odd things happens. There is a very unexpected behaviour on mid speed corners. In middle of the corner and without any previous advise the rear of the car slides and you can't recover it. It feels really odd, there isn't any force feedback signal that let you know what will happen, it sudenly happens. We tried several setup changes, height, dampers, differential, bump stops, bars, springs, but it never dissapears. It could be the rear tires stiffness, tire grip, or something on the aero. We figured out that using the front downforce at 3 never can't be matched by the rear even at position 10. So the best aero balance is 2-8 to 2-6. If you have some experiences like these, share your opinions.
