Funny if the fronts are 323lb, I chose 325lb for myself and feel it's really perfect.

I don’t know what’s goin on, but this winter all my long time project goals with hard to acquire parts are coming together all at once. Not sure I’m going to have any more mods I want to do, come spring.

Something like 385-685 from memory. Progressive. Fronts were like 143lb/in, but linear. Looking at the fronts, I would have guessed progressive as well. In fact, I wouldn't be surprised if the fronts were actually something like 143-300lb, but I have no proof.

I fucking hate companies that do that. Makes me want to just forget about their product and go with TCKs – my thought was that the FCM stuff seemed alluring down the road, so I wouldn't have to buy dampers twice.

If you have a moment, what’s the diameter of the front springs at the adjustment collar? Do they taper down to 2.5”?
They taper down to 60mm up front IIRC. I'm going to use a spacers or custom spring perch so I can run 2.5" springs.

Yeah, I just need height adjustable bilstein damper bodies. Not using the springs or stock valving, so paying more wouldn’t get me anything more.
... and if I were keeping the springs, the street setup isn’t far from the rates I’ll be running.

Any specific reasons why the Street Performance vs the RSS? Or did you just get the cheaper ones since the spring rates don't matter as you will be tuning those to your liking anyway?

The car was purchased with these on, so I never got to experience the OEM set-up (although I still have these stored). However, they give 1.27 vs the H&R 1.06 flatride. The ride height was set like this (Front: 640mm as measured from ground to centre of arch and Rear 635mm - same measurement) and the front camber was set to a smidge over 2° on standard mounts. It is/was very neutral and balanced with no ill traits. I'm now running different springs and dampers with much more camber thanks to Turner Hybrid top mounts.

Or...
If I'm reading this right, max front ride height is ~1.2" lower than stock. Is that correct? If so maybe the reduced camber gain in front balanced it out?
