Some observations after a quick race with stock cars at Salvador. First, most noticeable is tyres, more grip, easier more predictable feel, tyre temps more consistent. I liked the ultra stiff "go cart" feel of 1.15 but the new tyres are very pleasurable to lap on, and adds an extra realistic element. Car pulls more under braking, nice shudder under max braking Edit: There is definately a lot more tyre movement, low speed grip has improved due to the softer nature of the car, high speed cornering is more challenging, will be throwing out my setups for sure. AI, wow, it was good before but consistency suffered at times. Now a lot more believable, over all corner speed consistency improved by far, fast where they should be and vice versa. Pit lane entry improved. Hi res mirrors are nice. I have taken a minimal performance hit. Big changes but seems very cool so far.
