coilover spring 2.5" - barrel style (where to buy?)

My usual go to place of summit racing has a poor selection of barrel style 2.5" coilover springs -  they do not have the length or rate I need and for some reason I can't filter by barrel style.

a std 2.5" coil spring fits but I fear its too close and might mar up the threads on the coilover collar, plus I have to put the coilover collar on backwards for it to fit. 

where do you guys buy these things? and please don't tell me they are 90 bucks each...

12" length 180-200 inch/lb ideally.

Go to product category: coilover springs

Search within results for keyword: barrel

Edit: Added all your criteria and found 2 options, yes they cost $90 each, that's not out of line for an unusual specification:

Edit2: I've also spent some time looking for oddball coilover springs and sadly I've found that if it's not on Summit, it probably doesn't exist - even ran into a case where something was delisted from summit but not the manufacturer's site, but it was out of production so Summit was correct.

Have you looked here?

Coil over springs @ speedway

I won't tell you that they are $90

Pitstopusa usually has what I need.  55 versions of a 2.5" I.D. barrel coil-over spring.

I think you mean lb/inch, not inch/lb.  200 inches of compression per pound of force would not be much better than a piece of string.

A better Speedway link 3 pages of results for 2.5"

Many less than $90

Ground Control is the Eibach distributor for the west coast if not most of the US. Download the catalog, look up part number, order springs, proceed. $74.

Looks like Eibach has gone to an online database. Use the race spring lookup. No word on barrel, but I know they do offer them. A call to GC would probably be a very productive use of time.
