check the sway bar end link bolt... sometimes it's a bit loose if it's tightened down while at an angle and give you some noise

the sound like something hit the fender or bottom of the car.. not rubbing the fender tho..
imagine when the car is in fully stopped and just use your hand knock on the inner fender..
and that's how it sounds like.
THanks

Need more info.
How low is the car now after install? (mm)
Wheel and tire sizes?
Is it a "thumping" or "clank" sound?
Sound on both front wheels? Or ONE of the front wheels? What happens when you turn wheels and when you accellerate hard off the mark?

Is the sound a clunking sound? If so, it may well be the front sway bar end links. This happened to me in my G35 coupe after installing lowering springs. I suddenly heard this clunking sound when going over small bumps at low speed (20-30 mph). When I brought it to a shop, we saw that the front left end link was bent and that was causing the clunking noise. I replaced it with an adjustable end link which resolved the issue.
