Glad to know that I got the right springs.
No cool little "Made in Germany" stickers though...

I just tested pressures.
Yellow:
1.800" ~ 90lbs
1.250" ~ 290lbs
Blue:
1.800" ~ 95lbs
1.250 ~ 300lbs
The blue spring seems to coil-bind even taller than the yellow springs do also, so whatever the yellow's max lift was rated for, the blue should be lower.
For what it's worth, I think you'd be crazy to run either spring anywhere near .570" lift! They just don't have the coil bind, or pressure, to run anything very aggressive on, and you still see stock LS6 cammed setups with stock rockers experiencing valve float because of these springs.
For performance applications, run a performance spring!

Thanks for testing things Matt, I'm not going to be running anything over .540 lift in my 5.3 4x4 anyway and don't want a noisy valve train so I think the blues will work just fine. Thanks again for testing those springs, it helps me and I'm sure it will help someone in the future using the search button.
