Pic to illustrate why more roll stiffness is needed. This is just a steady corner, not coming down off a bump or anything. Dragging the outer corners of the aero on the ground. At Chuckwalla I could actually hear the scraping as I would turn into “dropzone” at the end of the back straight. I run disposable delrin sliders on the underside of the splitter so I don’t destroy it, but am wearing through those quickly:
During post-season inspection I also found scrape marks on the outer front corners of the side skirts. Not sure what corner that was happening in, but definitely a sign of lots of roll.
