When that happens the front end will lose grip rapidly. One of the solutions to alleviate this problem, is to deploy thicker front anti-roll bars to prevent the outside suspension component from compressing PAST the roll center and start to lose camber."
The advice I got from Dinan is that a little more front anti-roll bar helps a little, but too much more anti-roll bar hurts more than it helps. An e92 M3 ARB is a little more than stock. Your e93 ARB is probably too much.
