    True coilovers in the rear have a different wheel rate as the inboard config on a stock location spring. Darkman used the magic word "true". KWs and GCs are not true coilovers in the rear so the control arm has much more leverage on the spring thus requiring more rate as Fuzzy has recommended. For true coilovers Angelo's' recommendation make sense.

    Re: spring rates on REAR coil-over conversion????

    700 seems a little stiff for a daily driver am I incorrect on this assumption? I'm wondering if I should bump to 700/750?

    The 700 level is not too stiff for daily driving, IF the shock is set up to control it. In the two cases cited in this thread (Anze's Penske setup and LG Motorsport's setup) the supplier presumably matched the shock to the spring. That does not mean 700 is the right answer for any shock.

    Gotcha, so many variables with setting up the best suspension for your required use! Been reading grips of books on frequency, camber, caster, toe, rebound rates, etc but still a bit foggy..

    Dam. 900/500. Sounds stiff. Im thinking about 450 as a rear rate for my car. Keep in mind that the car make 875/860 and is used mostly for roll racing and drag racing. I also can NOT lower the car at all becuse of my charge pipe

    Oops. Sorry. I did miss that.

    I wish we had more coilovers options at reasonable $.

    Stock fronts with 450# true coilover rears will make for a very sloppy ride. You've essentially doubled the rear wheel rate while leaving the front wheel rate unchanged. The differing Frequencies could cause a lot of issues as far as handling goes.
