Check two-three things and see it they are the problem.
1. the exhaust. Since the whole system is tighter the exhaust pipe might be bumping the floor of the car. Because it is getting jolted harder, (I had this happen)
2. Check the heat shield at the muffler. Mine rattled against the hotchkis bar when I installed it. I had to bend the heat shield away from the bar.
3. check your bolts holding on the sway bar. If they are loose it will let the bar bang around on bumps.
See if any of this helps.
I have hotchkis sways and Ground Control coilovers, but I thought I'd throw in some advice from my problems.
