The coil over is connected to the wheels thru a quite clever and complex series of rods, and rockers. Most of this complexity is so that the coil overs can be located inside the body, so as to improve aerodynamics. The typical rear set up is often quite similar to the front.
This was good news in that the car behaved pretty much like a typical race car.
Here is a post by my friend, Diederik Kinds who is a Race Engineer on a team that ran the FR2.0:
I worked with this FR2.0 for years. It has an adjustable front ARB system with Bellevilles as depicted in the parts manual, but the pics are not the Tatuus FR2.0 but they look very similar.
There are a lot of Belleville variations for the FARB (preloaded and non-preloaded), none of which are modelled in iRacing.
When the iFR2.0 came out I immediately shot off a mail to iRacing about some setup inconsistencies - 1 about damping settings (bump and rebound were switched) which were subsequently adjusted and the other about lack of FARB adjustment.
I will just copy/paste the answer here:
"In regards to the FARB, essentially the stack system functions like a controlled, and exceedingly stiff, slack rate around center. Because most settings are much too stiff for our numerical integration step we've pegged bar rate to coupled installation stiffness and chassis torsion. This method was the only one, within the iRacing constructs, to allow all available RARB options. The alternative options would have been more restrictive."
On should always keep in mind that settings affect the car the way that iRacing chooses, "within iRacing constructs" as mentioned above ---and their choices may change from time to time. So always test to confirm settings continue to do what you think they do. The iRacing FR2.0 is an iRacing simulation of the real FR2.0.
You will recall that I mentioned that chassis settings often have to do with driver preference. I tend to think of drivers fitting into one of two major categories:
Softer springs tend to result in lower dynamic ride height, but often require a bit more compression bump damping.
You can test ride height with telemetry like Motec or Atlas, but a poor man's quick way is to simply use the iRacing replay camera, adjust the chase view so that your eye is at road level and watch the air gap under the car. iRacing will even display sparks when you bottom out!
