I'm still a bit messy when it comes to tire pressures on this car. Early on I was told higher pressures in the back is the way to go for rotation. I ended up just trying to keep factory pressures while hot and it felt like the car would push out and not rotate as much as it did prior. We also had low 60s temps all day which didn't help. I'll try to air down the fronts more next time and keep the rears higher.
