Default knocking when going over bumps

last night i was going about 40-45 mph on the street and hit a really bad pothole with my driver side rear wheel. Ever since then, everytime i go over sharp bumps, it makes a knocking sound which is really bothering me. I checked it out but could not find anything out of the ordinary. Any input would be appreciated. Thanks!

Current suspension Eibach ProKit on Tokico D specs and Spohn LCAs.

R U bottoming out and hitting the bump stops? Maybe the bushings are torn in the LCA's?

Check your exhaust pipes as they curve over your rear end. Mine were just a touch too close and would tap if I went over certain bumps ...

thanks for the tips!

but dont think the LCA's bushings are torn, they still look fine....

also, cant really tell if the exhaust pipes are too close. if it is, how would i go about fixing that?

Mine does this too lately, but it's coming from my front passenger side. I can't pinpoint it yet either.

I still cant tell if its a pipe or my suspension. If it were my suspension, would it make the noise on all bumps? In my case it doesnt. Only on small and sharp bumps.

On my 07 Mustang GT. The lound metal clink when going over bumbs ended up being a front sablizer bar End Link that had been damaged.
