Knocking noise from the near side suspension

following a trackday on saturday the M3 has developed a knocking noise from the front near side suspension. Suspect we hit a curb too hard, anyway jacked it up this evening and when i lift the hub the shock is moving about 2 mil at the top (the nut at the top of the shock, under the top mount) i removed the suspension and tightened this nut up which solved the problem until i drove it again the knock returned. i am guessing we have sheared two threads on the shock? Need to solve it quickly as I have a trackday at oulton on wednesday.

anyone got any experience with this happening?

forgot to add, its a KW suspension setup
