Just look at the bottom and top, and see if both are threaded.

 

Gotcha!

 

Some manufactures will call this "Adjustable preload" not "you can slam your shit with our product".

 

So will it have a collar on the top as well? Can you tell from the picture in the link above??

 

Yes, the top perch must be adjustable as well. Heres a pic of a preload adjustable stance gr+ coilover:

 

Yeah I was just about to say stance. I have the GR+ pro (pictured) and they go low...real low. There's a kinda pointless thread on NICO right now about which coilovers go the the lowest and the general consensus is Stance.

Oh and they're inverted monotube.

 

I have a chance to get just the fronts of these in this thread though and I only need front S14's....I'm starting to wonder if its even a concern since the S chassis stuff will make the Q really low anyway.....

 

True.

You could contact stance (and other companies of course) and see if you can get just the fronts. When I ordered mine I asked if I could get the rears with the z32 fork lower mount and it wasn't a problem. Their customer service is great.

 

I think I will. I talked to Tanabe today, they are not double adjustable...
