Some sets will feel better on some tracks than others giving the impression of more of less grippy tyres but that is not the case. It's just the balance that changes.
This is speculation but I believe that different tracks have grippier of less grippy tarmac and I believe this is the main reason for the difference in the way a setup feels from one track to another.
If you have a car set up perfectly for a dry track, most people like a tiny bit of oversteer mid corner and a little less in transition.
In real life if you then drive that same car, set up exactly the same, on the same track but it is raining you will find the balance is even more overtsteery. The reason is that there is less grip and because you set up the car for dry weather with a little less grip at the back than at the front you will find the back becomes very loose simply because there is less grip at both ends but the rear is a little stiffer.
Conversely, if you set up the car very understeery for the dry track then when it rains you end up with no front end grip at all and loads of understeer. It's exactly the same situation, just in reverse.
With this logic in mind it makes sense that one dry track compared to another dry track, one with more grip than the other will result in a different car balance in the same way that a change in weather does.
Ofcourse if Scawen pipes up and says "no - all tarmac in LFS offers the exact same level of grip" then my theory would be blown out of the water.
So, has LFS been designed so that different track surfaces offer different levels of grip? Scawen?
