Went to the track to test the LMP1 body out and I quite like it. The car pushes a lot more with the LMP1 body but the rear end is SUPER stable. In face, I think theres too much traction at the rear and not much down force in the front. I sauced the front tires entirely and left the rear bone dry and it still pushed.
I didnt do any setup changes with the car and still handled pretty well. Pretty surprised how stable the car was.
