Thanks for the info. Interesting how the PSS10s are the only ones who have similar spring rates front and rear.

Great overview,

some questions:
- what is the use/relevance of the wheel rate as opposed to the spring rate?

- I'm used to spring rates in SI (Systeme Internationale) and they are defined as force / distance: [Newton / meter, N/m]. With Lb being mass and not force, how do the mentioned rates mentioned here translate to SI-units?

SI spring rate value = Imperial Spring Rate value *2.2046 (for Lbs-> Kg) *9.8 (for mass->force) * 0.0254 (for 1/inch -> 1/meter) any thoughts?

- Is there any comparative info on the (minimum e/o maximum) damper rates of these systems available? Both SI or imperial values are welcomed? SI -unit is force * time / distance: [Newton * second / meter, Ns/m]

Late reply but here it is anyway.

Wheel rate is what the car actually experiences due to leverage. Just like a car jack, it is much easier (less force) to jack up the car when you have a longer handle. Same principle applies.

lb here is pound-force. Just google xx inch per pound to newton per mm.

This is actually incorrect. Its actually the exact opposite. Most can lower much more in the rear.

RZM3, I noticed you are missing the Nitron coilovers in this list. I picked up their 3-way adjustable a few months back and although its not yet installed on the car I can either send you the pics to upload or I can upload them in here myself? LMK!

Also, there are the following options:

JRZ RS1, RS, and RS Pro

Ohlins R&T

Motion Control Suspensions 1WNR, 2WNR, 2WRR

Moton "Motorsport" 2-way remote reservoir

Except for the Ohlins R&T, all other dampers use springs for your specific application (e.g., street-only, strret-track or track-only)
