Spring rates

[BA9092]

if you have a set of digital calipers/tape measure and measure the following, you can calculate the spring rate:

wire diameter
coil diameter
coil count
end/dead coils at installed height
material you can assume generic steel, the exact alloy is mostly irrelevant for rate

I can go further down the rabbit hole but I'll stop there.

That's too much math for me. Lol. I just emailed Eibach. Hopefully they'll come through.

I found this (Motortrend):
"Spring rate is the amount of force required to compress a spring 1 inch, while spring load is the force required to compress a spring to a certain height. For example, a 350-lb/in spring requires 350 pounds of force to compress 1 inch. A spring that compresses 2 inches under 200 pounds of load will compress 4 inches under 400 pounds of load."
The question is, how many inches does each spring compress?

650 ft/lb front
600 ft/lb rear (true coilover)
MCS 2 way Non-Remote dampers
Whiteline 24mm solid front sway bar
OEM rear sway bar
Verus UCW rear wing
Verus "low df" front splitter
Verus canards

I drive with my eyes closed on the track.

I’m over here trying to learn about spring rates and having a hard time with the ft/lb units. Everything I’m looking up is either lb/in or kg/mm. What am I missing?

Yea should be lb/in. I mistyped.
