If you are traction rolling, there is definitely too much grip on the track. You will definitely need to cut the tires down some. However, you should be able to lower the front by raising the knuckle.
Also, in high bite, what helps is less caster, less camber and maybe even some superglue on the sidewalls if you don't feel like truing them. I would really recommend to cut the tires down to no bigger than 43-43.5mm (even that is pretty big!) for the front and 1mm bigger in the rear. You will also find that the tires will have less of a tendency to chunk and the wear will even out. Remember that larger tires are effectively "softer" on a durometer, so this also will contribute to excessive squirm and have a higher tendency to flip.
