You should sort out what your doing with both anti-roll bar links on the car before you take it out again, and before you damage something like a brake pipe flexi!
Would be a good experiment to see the improvement in using the link to the strut instead to the bottom arm, it would give a more direct connection and take away the loss in leverage by going through the bottom arm.
Sorry to see the damage, but that's what a track day is for, finding the limits safely, OK finding this limit has cost some money, but you didn't go to the track without knowing the dangers, fair play to you, better than these idiots doing donuts in Tesco car park and endangering people by drifting on the road.
