Anyone have the motion ratio numbers? I have some data I'm trying to verify.

Front coils set at aprox 42% of wheel motion by my calculations on my car. My scrub radius was slightly more positive than stock with my brake package mount surface being about .300'+ outward. A standard wheel centerline motion to spring pocket may be about 43-44%.

How'd I know that you'd be the only one who would (or could) answer this? haha

Thanks 5.7, but it is quite easy to figure. You take the distance from the imaginary points between the mount ears of the lower control arm - to the centerline of the tire contact patch. Then the same from the ears center to the spring pocket center. The spring pocket center is aprox 42% and its motion of travel is parallel with the balljoint so there is no angle of reduction to speak of.

Now with the strut, it has more of a larger motion ratio since its lower mount is the spindle, yet the upper mount will vary in angle based on camber and caster specs PLUS ride height of vehicle. TH elower the car is, the greater the angle and the reduction of compression AND rebound rates. if the strut were mounted straight up? the motion ratio would be 100%. Mine is lowered and set back quite an angle with caster so mine I would guestimate quickly to be about 92-95% motion ratio of the strut in proportion to how much the wheel travels. So in other words, if the wheel hits a bump and travels upward 2", the strut shaft only travels about 1 7/8" aprox.
