Twisty,

I'm in a similar boat. Replaced pads with RS14 blacks, flushed with Motul, been to two track events since and either i am hitting the bump stops (front was too low) or else it's the abs kicking in too soon. I also have sport cups and they have way too much grip for this to be happening.
My car is still in the shop (steering pump gave out last w/e) so will ask them to check the sensors as well this week. Will let u know.
