Splitter held up well at Laguna Seca this past Monday. It was my first time at Laguna Seca, and first time running with HOD. The car felt pretty stable and confidence inspiring, almost too much so, I'll get into this later. With only the front splitter, there was some some slight oversteer with camber at -3F, -2.5/-2.7R, 0 toe all around. I was able to reduce the oversteer with adjusting the damping. The last session of the day, even though the tires were feeling a bit greasy, I was trying to see how much speed I could carry through turns 5 and 6. Turn 6 attacked the berm too hard and hit the red curb and ended up spinning, and cracked the edge of the splitter. Managed to park the car a foot from the tire wall, so I consider myself very lucky.
It was still held on with the bolt/washer and I just taped it for the drive home.
