does it affect aerodynamic drag in lfs?
last night i tried someone else's FXR/AS3 set. the set came from someone who is very fast, and it was very different than mine in every way other than steering. it was a bit wobbly in the corners for my taste, but it had 2-3 km/h more straight line speed than my set, even with me taking the corner exits slower than i normally would. i began to compare settings, looking for differences that would affect top speed.
total body and wing drag was nearly the same, so my next guess was gear ratios. i applied his ratios to my car, and it turned out that mine were actually better, so that theory was out too.
next i looked at the suspension, and noticed that he had 10mm of rake, while i had none. i lifted my rear end by 5mm as an experiment, and voila! 2 laps to warm the tires, then i put the hammer down and destroyed my pb by 0.3 seconds, with top speeds 3-4 km/h higher than i'd seen before.
so now i'm a believer in rake, but my question is, did the time come off because the aerodynamics are different with rake, or because the handling is better? because the downforce screen doesn't show any changes in drag when you adjust the suspension ride height.
