Rear suspension noises

[XLR Azn]

hey guys.

i juss got my suspension in. my set up is 17" rims, KYB GR-2 struts and coilovers. i've got about a 1.75 to 2 inch drop all around. but whenever i go ever a large bump on the street or take really tight turns, there's a large thump coming from the back. i juss want to know where that noise is coming from. thanx for ant help.

check ball joints if they have failed or if rear sway bar bushings (if you have one) are dry rotted or a bracket has broken off....happened to me before
