Default Mono Leaf Spring Rate?

I scraped the paint of my fiberglass mono leaf but still cant find a spring rate.. However, i did find some writing embeded in the fiberglass, does any of this info will help point me to a spring rate?

Hi

May be offtopic, so pls excuse me:

How is the spring rate measured or how can one measure it to find out ?

Was there ever a K value written on the spring? K=xxx

They take a spring and flip the spring upside down. A machine pushes the ends down x inches to find out the amount of psi it takes to push the spring down.

In very faint writing I found where it says "300" but I can find anything else.. Could the 300 be the spring rate? I know the rear end was like sponge so I'm pretty sure its a very soft spring rate.

Could be. It's it the same width along the whole spring (not paddle shapped) it's a very soft rate for a low arch spring. I wouldn't go any higher than a 330# sping on a high arch spring. It'll be a pain getting ride height.

Yes, its the same width along the whole thing.. I'm setting my car up for the strip so I was hoping this was a soft spring.

Depending on HP and Torque, we like to go with a much stiffer in the back. We like to start out at 360# on the low arch springs. With a soft rate, the rear will compress to much. Possibly even break u-joints and outer spindles. When your at full compression, the shafts need to be parallel. Not past that point.
