Roll out for a monster will be in the region of 26mm +/- 1mm depending on track size (carpet indoor).
The problem your stating sounds more like a suspension issue though, i would usually say loseing alot of ground though the infield due to bogging down would be because your scrubbing to much speed in the corners.
No dought your car is very stable and quiet easy to drive, just not as quick as the front runners through the infield ??
Try harder springs or possibly a roll center alteration to reduce roll and see how that feels
