Thanks for the good feedback.👍 I am curious, you reduced the downforce, and it seems to have gotten faster, I think that might work, I'll give it a go.👍 If you want to free up the rear end, changing the rear toe is the best way (since we don't have tyre wear) to go by the way you're describing. Increase the rear toe negatively (i.e. move slider left) until you achieve your desired result. The use of stabiliser bars would help too but we don't have them in Prologue.
Thanks again for the feedback, I'll try your suggested changes as well because best I managed was a 1'45.8.
