I did a reading before and after removing the pins on mine. I got an additional -.3°. Highly doubt it will make a significant impact on how the car drives but I’m hoping it will keep the tires from killing the outer sidewall at the track. From my research that was an issue with the FK8.
Sidewall stiffness is a factor but the amount of grip the tires have will still overwhelm -1* quickly. In my old FA5 I daily drove -2.7* all the time and didn't notice any extra wear over 10k miles over what the track does. Around -2 to -2.5* is a decent compromise between daily drive ability, track performance, and tire life.
Yea I'd love to get some more camber in it but I also really want to keep the car as stock as possible. I'll run this year and if it's killing tires I'll look into fixing it over next winter.
