Post a video? I can't even get the darn thing to copy a picture onto a memory stick...lol. Try my tune I posted a few pages ago, with the gearing set up the same way, not on automatic but on manual, shift around 8000 rpm no later, see what lap times you run. Using my same tune but with auto transmission instantly made me more than 1 second slower.
Try to not light up the tires under braking as it reduces traction and thus cornering and how early you can get on the throttle exiting the same corner. Especially important in the first hairpin. Into the sweeper (final corner), try turning in before braking but don't stomp the brakes, it only needs gentle pressure and then downshift (this will also slow down the car and bring the front end around as well) but try to do it so you don't either upset the balance of the car, nor slide out. You'll be much faster there if you don't break traction and drift out. If you keep traction and don't light up the tires, you can power out early for the front straight. You should be running out with four wheels onto the curbing on the left side of the track. If not, you aren't getting on the throttle early enough or carrying enough speed through the corner.
Another trick is the right hand kink after the second hairpin. Getting that corner right is huge as it carries speed all the way to the next hairpin. You should be taking it in 3rd and try to get two wheels up on the curb or even the grass. Try also to keep the throttle down at least partway, but ride the brake a little. This will give you better bite for the corner and keep the speed up. If you can't do that, you should still be able to do it just by lifting and not braking.
finally did a lap with manual transmission and did a 1:02.834 which is pretty irrelevant now I know lol, but whatever
