Loud Coilover/Suspension Banging

[GreenMNTDC5]

So I have recently installed coilovers on my car and noticed a loud banging sound from the right front, when going over small bumps or potholes.

I have researched, and I know noises from coilovers are common, but this seems strange for brand new coilovers with <1000 miles. I think it might have something to do with my preload on my springs. How much preload do you guys run? Would too much/not enough cause a loud banging??

Any suggestions, common issues?????

I just installed 300zx inner tie rod ends and SPL outter tie rod ends, there is no play, everything torqued to OEM specs. but when I hit a small bump it makes a loud bang, much louder than it should. I also installed new lower controll arms with new bushings on both sides because mine were blown. Tension rods, ect. Car is properly aligned, and I'm not low enough to be bottoming out so IDK

Help please!!
