    Turns out eibach makes a 6” long, 2.5” ID, 375 lb/in barrel spring, that they don’t offer except through GC... which will let me live my OCD to two decimal places.

    (going with barrel springs up front because I want to have the spring perch above the tire, so I don't need as aggressive wheel offsets, but then need all the travel I can get (as that pretty much limits me to a 6-6.5" long spring).

    Corner weights are a good place to start, though probably not necessary if your car is close to stock. If you can get them, though, you'll be more accurate.

    Jesse
    Yeah, he does a bunch more-- they'll be pressurized and valved to my corner weights and spring rates, bump stop tuning,and I'm having him add his KBO (similar but I believe superior to Ohlin's DFV) and ripple reducer.

    Nice. I'll be paying close attention, might end up going with something like that too from FCM. Will you be posting updates here or in a separate thread?

    I'm sure you saw, but Shaikh of FCM made an account and wrote some interesting posts in the E9X subforum. I'm curious to hear more about his experience with JRZ/MCS/etc and why he wasn't impressed.
    I'll be making a separate thread, but whenever I make separate threads about things I do to my car I also post them in my journal... so here, too.

    I had quad adjustable, remote reservoir JRZs and Motons on our e36 race car and was never particularly impressed. Conversely, moving the Ohlins to be flat ride was an absurd improvement that blew my mind. So… going whole hog, and trying the shock setup to match.

    Given that FCM only uses Bilsteins last time I checked, does this mean you're ditching your Ohlins setup completely? Are you going with revalved B6 shocks or something from the Bilstein motorsport catalog?

    FCM's insistence on Bilstein dampers is a weird stance (heh) to me given I can't imagine something like 2WR MCS shocks not blowing them out of the water with the same amount of setup, but I'm definitely going to give him the benefit of the doubt as he is a pro in this field and I know fuck all comparatively, lol.

    Getting a FCM suspension setup. I won't be installing it until this winter (as I limit my car disabling projects to winter), but money has been spent... so it's happening...

    Kind of excited, kind of scared.
    (scared because I've never driven a car that drives better than my does since I went to flat ride... so hard to imagine better than the best I've ever driven. But excited because I only went to flat ride in the first place because of FCM, so... here's hoping their shocks work to match).

    Interesting. I just rode in my friends car with custom built Red Shift coilovers. Been thinking about moving the TCK DA's and going with them. Cost is unreal comparatively.

    I'm probably going to make a thread detailing my journey through this, as I feel like a fair number of people are interested in FCMs offerings.

    ... but it'll be a slow burn of a thread. I won't be installing until the car is parked for the winter, and then I won't be driving it till the roads are clear of salt in the spring. So, realistically, we're ~9 months out on me driving on this setup.
