Fk hight sports all the way down on that picture.How have you gone about lowering the car? Do you still have the origional spring aids (bump stops) fitted?
Also as for removing the ARB it's really not a good idea, particularly the front one, however I am not sure how much difference it will make on a car that is so low, I can't imagine the handling could get much worse.
Just get some powerflex bushes mate. The arb will have far less movement that way.
are you sure its the ARB hitting and not the driveshaft or something else?
