Inspired since yesterday and with fresh ideas and a bit of luck I've had rather good day for D50 development. At first I have found that I can improve handling a lot by improving rear pushrods positioning, they were slightly off, and too short, not exactly sure how it messed up handling, but they do change a lot the way suspension oscilate. It is not the first time I am noticing that pushrods positioning is influencing the handling by a great deal. Then also lowering differential preload was quite helpful. In general car feels good with very small amount of differential locking.
Car now is still same, but it is way smoother now the way it breaks into and out of the slides, and it makes significant difference for pushing it to over the limits. Besides that it really does seem like the way springs are set up car feels good with equal stiffnes F/R, or with slightly stiffer rear, which is obviosly a little unusual for racecar, I think it might be due to cars sensitivity to snap oversteer from understeer. Apparently front TGM tires were little too large in diameter, reducing it also made good impact for handling. Understeering feels more natural and more useful now, but in general car likes to be driven without much slip front or rear.
Overal very happy with car now. I have approached the level of physics, where while testing I am doing enough laps to get to know what I need, and then I don't want to stop driving it
Then I also was quite lucky with gauges set up.
@ThomasJohansen now I have full picture with gauge faces and needles, it looks great, I only think now that I have chosen too small resolution for gauge faces and steering wheel mesh. I had trouble at first of needles not being visible, but it somehow got fixed, I don't even understand how. Great thing is that it turns out non-linear oil temp needle movement is possible, there are parameters for that
@redapg , although in skipbarber example there are only params for speedometer showed. It was very hard to understand how to set it up, and I still haven't properly understood how it works, but I have the needle moving in game almost correctly - starts too fast, then lags a little at 70C, then moves correctly up to 100C, and then starts going little too fast, and then lands on 120C pretty much correctly.
There were almost no pictures of the D50s doing a 4-wheel drift, except the 1956 model, a Ferrari D50, at Silverstone in the hands of Fangio.
This is what Dennis Jenkinson wrote after the 1955 Naples GP when comparing the D50 and the 250F handling:
Thank you, thats great read. Great observations, it does go along very well with pretty much there is to be heard about the car. I also think that they might have had trouble at seting up these cars s othey drove well, not only drivers having to learn how to addapt to different kind of handling. Maybe it was meeting half way situation, they were trying to get car closer to their liking and skills, and their skills also were growing into the car.
There are some slowmotion footage in first half of the video.
It is hard to observe four wheel drifts, especially on smaller angles, but drivers feel them very much haha
@gianluca Thank you this is great material. Although I should perhaps have better knowledge, but I don't know that much about the chassies of D50 and their sories, I only begun making this car twelve days ago. I prefer to model after original cars, over replicas, I might have taken refrences from non original car at some point. It is very difficult there were six cars, and they kept changing so much through every year, even before they stopped racing, and then after that god knows how many restorations. I think I like the one Fangio drives in Monaco in that wonderful video. Eitherway not aiming at high detailing right now, I am not even sure if to do riveting. Perhaps in future I would know better what could be helpful, not sure now. I can tell that while modeling at first it was hard for me to find references for drum brakes, that would show their detailing well. Also I think it would be nice to see the caps on pannier tanks better, although they seem to be rather simple objects, something about them the way I do is not right.
I have also just found plenty of great pictures there:

These are probably of same car as yours pics ?
@Corti Thank you ! This is pretty amazing reading material, some nice drawings too, I know what to read in the morning. Just briefly looked at the text - wow can you imagine it being 4WD ? I am currently unsure, but I think Mercedes also had plans to go 4WD if they would have continued racing. The history of motorsport would have been so different.
