When I saw this
I thought "Waaait, what?!" Yes, you see it too. The physics on both Kunos cars runs ahead of the visuals. But that isn`t the reason for the horrendous yaw wobble. That is simply the consequence of miscommunication between the two teams - physics and graphics. The later worked with the proper center of gravity (CG) of 0.48 front and the physics is 0.52 front CG.
Of course that means all the suspensions are incorrect and the behavior of the car is not what Stirling Moss once described as "The nicest Formula One car to drive".
Here I go again correcting all that`s not right and balancing the setup so you can enjoy it too and remember again the words of one true master after his win at the Nurburgring 1957: "When it was all over I was convinced I would never be able to drive like that again - never, I had reached the limit of my concentration and will to win." J.M. Fangio.
Installation: make a copies of the folders "ks_maserati_250f_6cyl" and "ks_maserati_250f_12cyl" in your "..\AssettoCorsa\content\cars\". Rename the copies to "ks_maserati_250f_6cyl_AB" and "ks_maserati_250f_12cyl_AB". Rename the sound banks in each of the two "sfx" subfolders to match the car`s folder
Extract this new physics from the "250F.7z" into "..\AssettoCorsa\content\cars\" and confirm to overwrite. Your DLC cars are not going to be modified and you will be able to use them as before. This adds two 250F`s respectively named T1 and T2
If you want more vibrations in the steering you can mess up the dampers on the front axle in setup and the FFB will look even more edgy than the above graph. Mind the effect of that on the turn-in and corner exit.
Some sources of info:
These two modified cars are not expected to work online.
