To get the F10 stable and drivable like the F2007.
I found that the two settings that had the largest impact were ballast position (longitudinal weight distribution) and LSD accel. Because of the ballast that brings the weight up to its real value, this setup won't produce quick lap times and has a tendency to understeer, but the car lets the driver be exceedingly confident in all situations, like the F2007. You can be very aggressive on corner exits without fear of snap oversteer.
The gearbox is set up to provide the closest possible constant-RPM-drop ratio set for gears 3 through 7, dropping 2625 RPM from 18k for those four shifts. It is impossible to get a closer spread within the confines of the game, unfortunately, so even in this best case scenario, first gear is entirely useless and second is questionable in most scenarios.
To set the ratios,
(1) Reset to default
(2) Push top speed all the way to the right
(3) Push final ratio all the way to the right
(4) Push top speed all the way to the left
(5) Set the ratios, including final
Well this is one of the best setups that i've been trying for a long time.
no oversteer or understeer at all.
I got a lap tim on nŁrburgring nordschleife 5:49.392 (without crashing)
I run it with 4 in Controller steering sensitivity and 1 in ABS so it understeert a littel bit. (i change that to a 2 like your setup)
