Thank you very much! Indeed there's a massive difference between front and rear roll rate, I see that's because the rear suspension is stiffer than the front, look at Suspension Frequency you want those numbers to be close. Try a most inner arm shock hole and keep the same shock angle, also pay attention to shock piston hole and oil starting recommendation, those are the very base of the entire process.
I saw some numbers outside the usual cells, would it be better if I made changes to the layout to improve something?
