Front end clunk

[porsche735]

I installed new lowering springs in my 2002 Cab and I now get a clunk in the front end. I had the same issue occur on my 2001 after I added the springs, but thought it was something else. Now, after doing the same operation to the 2002, it is there again. Anybody have any idea what could be clunking with this lowering? It seems to get worse when there is a passenger (lowering the car further), and also under light braking.

Thanks,
Chris
