Help Identifying Lowering Springs

[dablaze313]

All, I just bought a set of used lowering springs that were advertised as the Kenny Brown Club Sport springs but wanted to get y'all's opinion. Here are a few pictures I took of them. I can take more if it would help identify them.

In the pictures the seller sent me the fronts appeared to be black instead of blue (crappy pics), leading me to believe that they were the KB springs. I still think they may be as their geometry is very close to the few pics of them I can find online but the color is throwing me off, as they are supposed to all be black and don't appear to be repainted. None of the springs have any markings, which I expected since they are old. Thanks for any input you can provide.

Here is the only thread I could find on here that had pictures of the springs themselves. http://www.svtperformance.com/forums/suspension-modifications-211/830339-what-springs-black.html

Get some calipers and take the required measurements and you can determine the spring rates easily. May not be 100% exact, but you can get close. If they are KB springs, you got a great set since the rear springs have a HIGHER rate than the front - perfect for nose-heavy, understeer-prone Cobra's.

No I'm sure they used to have markings on them but they look well used so I bet they wore off.

That is my plan as ball-parking the measurements with a measuring tape gave me horrendously low spring rates which I hope aren't accurate at all. I had previously read from various sources including your posts about the benefits of having higher rear rates for IRS Cobras and so when I saw this set come up I jumped on it as KB springs are hard to come by nowadays.

For those wondering or in case anyone else comes across a similar set of springs, I believe that these are in fact Kenny Brown (or Engineered Performance) springs. The rear springs worked out to about 820 lb/in and the fronts about 720 lb/in. I'm amazed that I got values so close to the published ones using a cheap Chinese pair of digital calipers.
