I only have the spring rated KW v3 and Clubsport. Both will induce under steer without bar change. The motion ratio for the rear is about 0.35 after being squared. The OEM frequency between front and rear is dead perfect (not surprising) and one should aim for about 10% higher frequency in the rear than the front.
If someone wants to measure one coil at time on the Dinan front spring I can calculate the spring rate. The rear is same method but much easier. I am still curious what the supposed outcome of the Dinan bump stop investigation is…a purpose to an end. The shorting is just in proportion to bump travel….it is fairly straight forward and expected with increased spring stiffness. I would just phone them and ask. Orb |

Lucid, I ran a few hand calcs and the spring rates make sense. I guess we just need to test the aftermarket springs now? Last edited by rzm3; 11-24-2008 at 09:40 PM.. |

As you know, spring rate is a function of displacement. To completely characterize the behaviour of the spring+bump stop, I'd like to take data on the entire operational displacement range. I doubt that the springs will be perfectly linear, and then there are the effects of travel on the bump stop. My goal is to come up with a complete effective force displacement graph including the part of the displacement that is on the bumpstops. I should call the dealer to see how much the bumpstops cost. As you said earlier, they should be fairly inexpensive. I checked with my friend and he says he has a way of keeping the springs stable, but I'll run the dimensions by him to make sure we are OK.
