Not sure if your asking about the car's suspension bottoming out or if the car itself is hitting the track.
In GT4 you could tell the car was bottoming out and hitting the track, the easiest way is by watching a replay or following a car that has bottomed out on the track.
Watch for the sparks.
I would imagine every time a car goes airborne at Eiger it would certainly bottom out the suspension and maybe have contact with the track.
In GT5P there are no sparks so it would be hard to tell. I would still think watching replays would be the best way.
If your asking about the suspension reaching its limit and hitting the bump stops and/or contact with the cars body, I myself can not feel this happening. Now all of this depends on the suspension settings as most of these cars are driven with low ride heights so I would believe they would reach the travel limits (hitting bump stop) quite often.
Now the bump stops on these cars may also be at a height not to let the suspension hit the track when also limiting the front splitter from contact with the track.
Maybe these are areas that PD set and can not be fully changed in settings so as not to set the suspension too low. As we know in real life you can certainly set up the suspension too low and drag all kinds of car parts on the track.
So without sparks I can not tell if the car is dragging on the track or bottoming out the suspension.
Probably not the answers your looking for but maybe a little insight.

I dont think sparks tell you when your bottoming out, some cars did it all the time, others never and they were equally low... i think its super hard to tell in GT games simply because you cant feel it with your ass, just dont lower the car too much and if your spring rate is too low youll notice the front dive and hit the road, i would imagine that would tell you its a little to soft up front, just watch replays and see if the suspension is compressing too much..

Bottoming out is two things, hitting the road, which won't happen in road cars only race cars.
The other is running out of spring travel,which is most likely this is difficult to read. Raising the ride height and testing the grip in hard turns, is the only way, I guess.
If the car continues to understeer, it's probably not bottoming out. No change possibly means the car is at it's potential unless you can harden the spring.
If you gain some front grip, then it probably was bottoming out.
You will have to lift the car the same amount front and rear, from your current settings to get a true result from this test.
Good luck:tup:

If there are no sparks and/or no understeer does that mean that in GT5P we can drop any car to its lowest setting available and reap the benifits at least until GT5 comes out? No "bottoming out" in prologue? I am confused.

Not a pro tuner, but I like playing around nevertheless. I think you can feel bottoming out (I am only referring to the cars suspension-travel reaching the limit) by paying very close attention to your forcefeedback (given you are using a wheel) and the cars balance.
To experiment: set a car's suspension and damping as soft as possible and the right hight up. Run over curbs, see how the steering feels and whether the car gets upset (it shouldn't really). Now drop the car massively but keep the suspension soft. You should now feel the ff kick in harshly as you rumble over curbs, the car might also kick out of balance. IMO THAT tells you you are going over the suspensions limit and thus bottoming out.
To the tuning now: drop the car so much to reduce weight shift as much as necessary, depending on car of choice, then increase the strengh of the suspension just enough so the car just doesn't bottom out anymore. That should (theoretically) give you an ideal compromise between handling and grip)
PS: I'm not the fastest around here, so this is just my opinion and what I do, but maybe it does help you a bit with your question.
