    E34 Coilover Spring Rates

    Hi,

    I am looking into coilovers, I will likely get some BC coilovers and I am debating what spring rate is best.
    Like this: BR Series Coilover : Type RA - BMW 5 Series E34 89-96 - BMW - Applications | BC Racing Coilovers

    Their default setup is F:7K R:6K


    The next step up is F:8K R:8K

    This is for a road car (turbo M5) that will see some drag launches and track days (nothing too serious).
    I do value confort and compliante over outright performance.


    Anyone with coilovers has some tips?

    Thanks

    I forget what rates they use, but I’m about to install ISC Coils on my e34. I have a set of them on my Z3 and they improved the ride (was on H and R springs before) while also making the car handle ten times better in hard corners and transitions.

    Anyone with spring rate input.

    Is 8K 8K too stiff for a daily?

    All depends on the quality of your roads. I went 10k/8k for mine in the 540i and on Australian roads it's very 'daily' friendly. Corners flat but quite forgiving over bumps.

    I too wanted something for spirited street driving and an occasional track session.
