Seems like a decent mod, but they've apparently "fixed" the tire model
so that it's harder to slide the car around corners. I ran a few laps
at the 67 Spa track (which, if IIRC, was taken from GPL) and found
that I was many seconds faster in the Ferrari than I ever managed in
GPL. I also found that there was *way* too much steering input and I
couldn't for the life of me figure out how to dial it out of the
setup.

Even with castor turned down to about .5, I was really unable to hold
the car in a straight line for any length of time, and the slightest
wiggle of the back end resulted in heavy oversteer -- leading
inevitably to the nearest fence or building. <sigh> I must admit that
it might be the RealFeel FFB that could be throwing things off. I
also should admit that I know diddly-squat about setups, although I
can get a modern mod to at least steer properly (that's "properly" in
my own opinion, of course.)

I'd be interested in trying out any setups that anyone else has worked
up... As it is, I just find it's too much work trying to keep the car
going where I want it to. Maybe an online race would reinvoke some of
that old GPL excitement though.

==========
The only thing I can add is that it drove well for me at the 'ring. I raised
the ride height quite a bit because it was really twitchy if you touched a
curb. It took speed well, and did 8:30's right out of the box on the full
Nordschleife ring with only the ride height and gear ratio changes. I don't
recall tweaking pneumatic trail to soften the response, but I might have.

Lowering caster will make the car more unstable. Adding caster adds
straight line stability to the steering.

Hmmm. OK, I'll believe you and try cranking the caster back up again.

Can't make it any worse (I hope).

I had to adjust my FF from -100 to +100 with RealFeel in the RF Options.

Andi.

If lowering caster made it less unstable for you, I'd say you have
your FFB strength setting reversed per Andi's suggestion. Otherwise,
increasing caster will always create more stability.

I'll explain why it works that way just so you can believe me

In suspension geometry, 'mechanical trail' refers to the distance that
the contact patch of the tire follows the intersection of an imaginary
line through the kingpin through the ground. The larger the
mechanical trail value, the more of a stabilizing effect it will have
on the direction of the tire. Increasing caster points the imaginary
kingpin line further in front of the tire contact patch, which
increases mechanical trail.

For example look at the front end of a bicycle or motorcycle. Ever
notice how the forks always either angle out in front of the head tube
of the frame, or the forks will be bent forward near the front hub?
Same thing - that increases mechanical trail which increases stability
of the bike.
