West, is your car too lose?
You are braking quite early. 1:44 is fantastic no doubt. You can cut down even more time by working on those brake zones. I’m not sure if it’s a driver thing or a setup thing. I suspect that your car is already a little too loose as is, and prevents you from hitting the brakes as late and as hard as you should be. I bet if we had a G force reading, we’d see this. You’re getting most of your braking done in a straight line, and you are on the gas before the apex. Very HPDE, not the fastest way around a corner type style. Maybe that’s your style–nothing wrong with it–just know that you can shave even more time! Would be crazy to get down to 1:41. I bet the car has it in her.
For most corners, your speed is anywhere from 3 to 6mph slower than when your car is pointed to the apex. Suggests you either braked too hard, or too early. I suspect your car may be a little hairy on entry, and the whole idea of putting on even more rubber up front may not help things. Have you tried disconnecting the rear bar?
What tire pressures are you running? Something looks very off in your videos @_@
