Sorry Mods but I need to copy and paste my post from the other thread to here. Not sure why people are not getting the difference between career mode and Time trial.
"Career mode uses full simulation so tyre wear, fuel loads, differing track temperatures, and cars are scaled as they are in real-life, with Mercedes being the quickest, Red Bull having better turn-in/less power, and cars like Sauber, Marussia and Renault all being the slowest. Time Trial setups do not suit these conditions.
It's not impossible to use TT setup for a race, the balance should be Ok, but you will lose time down the straights and have more tyre wear. This is because downforce/camber/roll bars (etc) levels are adjusted to have DRS (sometimes twice) for the straights on TT where DRS is guaranteed despite no cars being out on track. You won't get DRS for every lap in race conditions unless you're fighting close in the middle of the pack and can follow others; which is very unlikely. Therefore TT setups need tweaking to compensate for race conditions. I do plan on posting race setups after I completed all TT but it may be some time."
So in other words. DO NOT USE TIME TRIAL SETUPS in career mode! Or for any race in general. I don't understand why people are getting confused. It specifically says under every one of my setups it is a **Time Trial setup**. Perhaps I need to post in Caps Lock under each of my setups "DO NOT USE THIS FOR RACES" .. or something. I may have to go back and label them all as such so I don't have to repeat myself.
