Im asking this question because I forget what i did.
So im wondering what would have been the most logical thing to do at the time.

A few weeks ago i removed my stock suspension and replaced it with the Tein SS Suspension (w/o pillow ball upper mounts).

I am now replacing it back to stock and im looking at purchasing an OEM used set of suspension from a person, they said they do not have the "hats".

Now im wondering, would have i used the ones from the stock suspension for applying this suspension on? My thoughts are yes, but I cant remember exactly and im in a somewhat doubt as to knowing what the "hat" is.

Any help, photos, or anythign would help.

 

yea, buy mine. complete....make an offer....and i think u can use your stock hats on aftermarket setups, the quality won't be up there, but im pretty sure u can....correct me if im wrong ne1

 

The "top-hat" is the thing on top of the spring and where the strut rod bushings are housed in, right below where you tighten the shaft of the strut.

You can use factory top-hats on some aftermarket struts/coilovers as long as the shaft fits through them.

 

my guess would be no you didnt reuse them because the tein ss come complete assembled so there was no need for you to compress the strut assembly and swap over the top hats
