rob pasted me the vids so I gave em a looksy, good lines with some honest mistakes, but you commented them all yourself, so you know which is a good thing
to much curb makes the car unstable and is not good, on some tracks you can't hit the curbs at all in some turns, while on wet you DONT won't to hit any curbs so thats a tip to note.
when letting the car out you wanna pretty much drop it either on curb all the way out if flat and try, or on exactly the white line if rainy or no curb, no more no less.
now when it comes to brakeing, stay 0.5cm from white line as if you hit it with a wheelset you will have uneven traction and get a unstable car under brakeing.
with a whole lot laps more you will be able to do this perfect I think, and will also take the experience to other tracks, new tracks is always hard, but if you have a good base it sure helps!
what setup are you running on the car? suspension? pads? wheel psi? wheels? tires? camber front&rear, toe in front, caster etc?
must say it really appears to have good turnin on the video, and a good even power curve. but everything can be improved! as an example here on our local tracks we can race with uneven psi/camber for getting the last few nano seconds
(only for small courses usually)
what pads are you running on the k-sport, and have you measured caliper flex? a tip can be to have them drilled with a few extra cross braces.
