First of all, hi all!

I'm just a demo racer at the moment, but I have a couple of questions I need answering before I can improve further:

Is there a "ghost car" option in this game anywhere, and if there is, it is generally helpful in improving lap times?

Second question (ok third technically): I am using a downloaded setup and when observing the tyre temperatures whilst racing, I notice that the camber is setup so the outside of the tyre is generally undergoing more force, causing that section of the tyre to overheat well before the rest of the tyre. Is it a good idea to adjust the camber until the tyres heat up uniformly in a race, or are there other factors that influence the decision on how to set camber?

Big thanks for any help in advance

Hello and welcome. There was a ghost car mod which I found very useful actually, but not sure if it still works for the latest version or if it will work with the unregistered demo version.
Regarding tyre pressures, it is always a good idea to spread the wear over the entire surface, so once you get even heat-up distribution the grip of the tyre will be optimised. Keep tweaking with it till you're happy and you should find it gives you optimum grip for longer.
