I am still looking to grasp all the ins & outs of the game and stumble against another topic where I am a bit wondering how things work. For some cars we do have a regular and a low downforce version, which in most situation alter how the car looks and also use a complete different "car" in-game (you have to recaliber your seating position, settings are saved differently,...). I did not sped time testing older car like old GT1or Group C car, nor the formulas cars, as I still learn the game my main focus is and remain modern GT. I went out to test the Z06 (again) to figure out what are the differences, as for modern GT I could not notice anything different model wise, unlike formula cars and older GT that clearly have different 3D models. To conduct my test I used Le Mans which luckily offer the chance to have use the two different specification on the same bit of track, namely the run up from the Ford to the Dunlop chicanes, thansk to the Le Mans and Bugatti layouts. I used the exact same setup, including the wing set at 5 in both cases. I could not spot any difference in car behavior, but also had the exact same speed of 251kph at the apex of T1 leading up to the braking zone of the Dunlop chicane. So here is my question, for modern GTs (GT3 g2, LMPs and LMDh), what is the difference physic wise in the game engine between the Low Downforce and their regular counterparts ? Sorry for the "noob" question and again I did not test any other category of cars which clearly show a more pronounce difference in their 3D models.
