Had a chance to put in some real laps and got down to a consistent 1:10.0 and a best of 1:09.803. Main difference was discovering that the default higher downforce worked better, I then added 1click front aero and removed 1 click of rear aero. For sure there is more time to be had but I think I will go crazy if I try to force anymore speed from the default setup, which isn't so great.
