Has anyone performed measurements of the Mazda3 suspension system to calculate bounce frequencies? I'd like to do some desktop engineering and figure out spring rates and sway bar calculations, as I figure out my next project car.

Motion ratio: Front (strut) ~.95, Rear (spring cup) ~.7 Corner weights: depends. The Gen2 Skyactiv I have was roughly 900lbs per front corner, 550 per rear corner. Never bothered to calculate for stock springs, but I came out to 2.0Hz being achieved front and rear at 8kg/mm front and 7kg/mm rear springs.
