I bought the raybrig nsx and tuned it a bit. I tried to improve the car with as little setting changes as possible, as an example of how to remove the problem your having.
For starters, I suggest changing LSD initial to 30 and negative camber to 2.0 front and rear. Another change you could make as default is toe at 0.00 front and rear. I think something like this is a good start point for any MR or FR tune. With camber too low, it's just hard to get anything to work good.
I like having high initial and accel settings, the high initial gives the car a more direct feel and more control. I think it also will help with reducing oversteer on corner exit, after I add the other measures to remove oversteer, if I the lower the initial, the oversteer comes back through some corners.
Having high accel setting might prevent the car from turning well through extremely tight radius turns. It's only as a turn becomes too tight that a strong LSD prevents the wheels turning at the required rates. Therefore, you will notice a car get loose at the
apex if the LSD is too strong, which might have just happened once as I was testing the tune (but it was no big deal anyway).
Anyway, I found two easy ways to tune out the oversteer.
method 1
LSD: 30 / 40 / 20
ride height -6 / -6
neg camber 2.0 / 3.5
toe 0.15 / 0.15
method 2
LSD: 30 / 40 / 20
rear spring rate: 17.0
rear bound: 10
neg camber: 2.0 / 2.0
toe: 0.00 / 0.00
(also this would not support backwards suspension theory. See diagram in
this thread.)
As for the yellow hat, I can't help because I'm not getting any oversteer with this car.
