Measuring ACF (Angle Correction Factor)
I've put together an excel worksheet to run some models of different spring rates and their effects on suspension frequency and "flat ride" target speeds - assuming I even want a flat ride. One of the inputs is the Angle Correction Factor or ACF, which requires knowledge of the angle from vertical of the front and rear springs. I went ahead and assumed 10 degrees for both front and rear just by eyeballing it. It might be off be five degrees or more so I figured I'd ask if anyone knew or had measured the angle on their own e9x?
