I ran higher in rear and softer in front by 4 psi. Used chalk to mark tires on my first autocross run, and looked how far the tires were rolling over. Then I Reduced the front pressure to 32psi and the roll over the side was nearly perfect on both. Was a cooler day though and cool pavement. Note I’m on 265/35r19 fronts star spec PSS and 285/35r19 rear PSS regular spec. I’ll continue to use chalk on first run to see what I need to adjust. For me it’s easier to go down in air than up as my pump is slow. So I start at 36
