Unfortunately, was unable to salvage the GoPro video of this lap so I am using the dashcam footage instead. Managed a huge PB in great morning weather today at Sonoma Raceway.
Even with the increased front camber, the car still terminally understeers everywhere, but much better than the factory -1.7 degrees.

Started logging oil pressure, and noticed that there are huge oil pressure drops (down to 20psi) almost every single braking zone. Perhaps a baffle would help fix this? Running a small overfill later in the day did not seem to help the pressure drops.

Full setup:
Front Camber bolts in lower hole
Alignment: -3.5F/-2.3R, 0 toe all around
235/40/18 Continental ECS02 Tires (340TW)
Stock brake pads, wheels
