I am not familiar with cars that run better than 1.2+ 60 fts, but will offer what I see. Looks to me like you nailed the setup for a fast surface/best scenario but this day was much different. By that I mean the rear suspension is not hitting the tires, you use torque and available traction to get needed weight transfer. The surface won't handle the hit without a softer rear shock and shorter IC , or maybe one or the other. Same with the front. It didn't even try and rise.
You might have to start with a setup that will handle this type of track and see just how much that setup will cost you on a good traction day. You may be able to leave it close to the same settings, maybe not. But it should have at least let the wheeliebars touch the track on the hit, IMHO.
What was the track temp?
