I recently put WCC lowering bolts on and now it seems that the sway bars front and rear are hitting my control arms when I go over speed bumps. Seems to be worse in the back if I hear it correctly. I will probably just raise the car up a little bit this weekend but wanted to see if anyone was having this issue too.

Id be willing to bet your hearing something else because the sway bars should not come that close to the control arms. I was lower than the bolts you have before the coilovers and Im just as low now with the coilovers and I have T1 (bigger) sway bars and they dont come close.

I thought the same thing but at the encouragement of forum guys, went back in and re-tightenend all the bolts and the sound went away - they need to be REAL tight.
