ok here goes i have a 96 honda accord i like it low ive had tien coilovers and now have d2 1 piece coilovers the problem i am having is a banging only in the front when hit a decent bump thought it was the suspension so i switched but same problem thought it was the control arm hitting the top of the wheel well so i cut out a slit for that not smart but still same problem to low im guessing but anyone knows somthing i dont please let me know thanksssss...

 

More than likely you omitted the "Jounce' bumper (that rubber donut which slipped over the strut shaft) and now the strut is running out of travel.

thats what i thought but the new suspension i bought has a seperate height ajustment and alows the shock to have full travel at all times i dno thanks thoughhh

 

I suspect the "seperate height ajustment" has been set too low.
If it's a really hard metallic hit, then I suspect the struts' piston shaft is hitting against the bottom of the shell (whacking the compression valve assembly). Continued use will probably blow out the strut.
