I see this topic get brought up all the time so I would like to make a sticky of it. Here is all the information that I have found about it. Please feel free to add this this thread with anything else you guys think might be useful.
Pedders (Cobalt Spring) Everything from CED and Qwik
I bought every piece new. It ran $900
Qwik makes you the spacers

#10 (Cobalt) Nut 22716359
The rears are the same install as ION springs. Make sure that the rears look like a beehive or they are upside down.
You might have to lube up the bottom post and #10 to push it into the spring, but the car's weight took care of it for me.
When taking apart assembled struts, you have:
The struts are completely compatible between the Cobalt and Ion
The bottom of both springs are the same, where they attach to the strut.
The top of the cobalt spring taper and are narrower than the Ion spring, requiring a cobalt hat to be used.
The Powell adapter spacer is very small, and allows the cobalt hat to be used with the Ion Strut mount, because the hat and mount need to be able to rotate independent of one another for the car to turn.
The Ion and Cobalt strut mounts are COMPLETELY different. The cobalt uses a standard 3 bolt mount, which allows it to be shorter and really is a better design, but the Ion uses a single bolt mount, making it taller and generally silly in design.
So, to do TC struts, you don't need any adapters or cobalt parts.
To do ANY cobalt spring on an Ion, you need a cobalt hat and Powell's spacer or a similiar fabricated spacer. I will not give out the dimensions of the needed spacer, so please don't PM me for that.
