New/Used JRZ's, how to find Hypercoil Spring ID

[Scin]

I picked up a set of used JRZ RS coilovers. I haven't been able to get the spring rate from the seller.

Does anyone know where to find the ID on the spring, so that I can figure out the rate?

Hypercoil doesn't mark their springs like Eibach does. They engrave the top (flat part) with a number which is the spring rate.

Thank you sir. I was able to find the rate on top. It looks like I have the 300/350 setup from Jon Martin.

I ordered 450lb fronts to use with the 350lb rears. I will try that out and see how it does on the track. I will probably do 600/front 450/rear at some point in the future depending on how well 450/350 works.

Let me know if you need springs, I have 1000, 800, 700, 600, 500 springs (pairs) sitting in my garage.
