Default Suspension/ eibach springs rattle

Hi guys and gals
Can anybody help shed some light on my little concerning matter?
I have just fitted some Eibach springs to my 05 wagon using the original shocks.
Its not new to me as i have lowered cars before and all seemed pretty familiar, taking my time and remembering what went where and what.
After all four corners complete and all bolts checked to torques required the wagon was taken for a spin.(mind you that 17mm top nut is a bastard to tighten and check torque settings!!!)
All seems OK, feels harder obviously and much more responsive in the corners with no noises from general driving even in the corners yet i get a slapping tinny sound from the front when i hit pot holes and rise up over speed bumps at an average speed for a lowered car.
I keep thinking to myself is it the new spring rungs slapping as they close up together or in the bottom cups due to me cleaning out all the crap that surround the originals.
I have taken a second look and nothing seems out of place or bits missing! The only thing i notice is that the new spring rungs are very close together on the front as on the back yet they have a sort of neoprene tube on the bottom half as they are very tightly wound.
Should i just give them time to bed in??????

Since the last post both front shocks have been back off and striped down, nothing unusual found nor anything wrong!
But during reassembly the second time around i did wrap some self amalgamating tape (rubber with no adhesive) around the lower quarter of the springs making sure it was neatly overlaped.
Once all was rebuilt and a test drive undertaken all is good!!!!!!
It must of been the spring in its lower seat knocking with metal on metal over bumps in and out of load!!
Fingers crossed all stays good

Post edited has done a search to remind myself what I did.......

You have to make sure the top hat on the front shocks goes on correct.
You should mark the top hat in relation to the bottom cup before removing the old spring.

Do not fit the top cup so that it sits snug on the end of the new coil of the spring.
The shorter coil spring and different postion of the sprin end will cause it to be in a slightly rotated and hence puts it out of alignment.

it's an easy mistake to make.
If this happens the cup/spring rattle and/or the cup catches on the inside of the tower.

Cheers fella for the info!
I remember when taking the shock apart that the top hat and bottom cup when viewed from the side both had a matching angle that followed the spring coil shape.
I even marked the very top bearing section that consists of three 12mm bolts that bolt through the top mount before removal. This part when spun on the shock when out reveals its not symmetrical but slightly offset.
Well ill drive to the meet today and have a proper drive and listen but all seems good and i feel better now Ive rebuilt them twice with a second pair of eyes on the job!!!!
