File Name: Basic Spring Setup Tool File Submitter: Alessandro Pollini File Submitted: 02 Oct 2011 File Category: Patch & addons Author : taufikp This is a browser based tool, because I want to be able to use it anywhere, from my smartphone or tablet. Some say that it is easier to do initial spring setup based on known natural frequencies for specific car type. Some also say that these frequencies can be used to get good balance between front and rear spring rate. And of course this "math based" setting is purely for basic/initial car setup, after that you still need to do some laps and change some settings, in order to get good car setup. I created this tool in order to learn (relearning to be exact) car physics, especially the correlation between front spring and rear spring frequencies/harmonics. How To Use First, you need to enter: - weight - weight distribution front-rear - lateral weight distribution - all spring rates This tool will calculate and show you: - frequency for each spring - total average frequency at front and rear - recommended rear spring frequency There are three recommended rear spring frequency values: low, medium, and high. Change both rear spring rates (left and right) to mach the recommended frequency you want. Click here to download this file
