Some peope say that lowering the roll center creates more roll in the car therefore using the tyre less and stopping traction roll
Some people say that raising the roll center creates less roll which prevents the car rolling too far and grip rolling
any ideas?
It depends. Typically when you use a higher roll center it can make the car traction roll if using too stiff of a spring. That usually happens at the beginning of the corner of if you change direction really fast.
Lower roll centers have peak grip later in the corner (kind of like what you have going on), especially when combined with too soft of a spring.
Maybe go back to 1.5mm suspension mount shims up front? You can also widen you car too. Maybe add a spacer or something on the wheel hex hub? That should help the car be more stable and less tippy.
