just got a eibach prokit installed like a week ago and today when i was driving i hit a pothole and heard like a banging sound coming for the rear,both sides. it kinda sounds like the car is coming down on the springs cuz i heard a coil like noise once also any ideas?

 

Did they trim the bumpstops(I think thats what its called)?

 

either that or they put them in upside down

 

I've had the same problem for the past month. I had the prokit and AGXs installed then, but haven't had time to address the clunck noise until yesterday. I assumed it was something Suspension related because that's what I had worked on. Seemed logical at the time

Turns out it's actually my freakin exhaust hitting the bumper. When we installed it we just used the stock hangers and that was fine for a "cushiony" ride. Now the thing bangs on any medium to large bump. I'm headed out with coat hangers in hand to try to secure it now.

 

is the same problem I had, the coils at the top of the rear springs are hitting each other, go to honda and ask for part #52442-SM1-A00, you will need about six of them.
place them at the top of the spring where they touch.
check
