  1. Hello everyone! I am a graduate from Kettering University (AKA...General Motors Institute) and I took a vehicle dynamics course while I was there. Apart of the class was to create a portfolio for one vehicle within each group and of course I chose my 1989 Jeep Comanche (Eliminator package) to do my portfolio on. The calculations within the files below were calculated using both CarSim (simulation software), in lab measurements (in garage, using weights and measurement tools), and vehicle dynamic equations. Below I have the power point presentation and excel document Google Drive links that have the raw data for my 1989 Jeep Comanche. The excel document is read only. ***FOR BOTH the power point and the excel document, click on the links below and you should be sent to each file in google drive. If you cannot click on the links, copy and paste these links into your web address bar at the top of your web browser. After that, download the files by clicking the downward facing icon near the top right of the screen. You need to do this so they look and function better since the files are Microsoft office files. Google drive doesn't like to view these files sometimes so it is best to download and open these files with Microsoft office.*** https://drive.google.com/file/d/0B52R0MdRNDTlYml2Nm1LMUo2NTg/view?usp=sharing - PowerPoint Presentation https://drive.google.com/file/d/0B52R0MdRNDTlMFp5VDNfbGVlZTVBUTRqQU5tcHRZQUIxVUJZ/view?usp=sharing - Excel Document There are a lot of parameters that are laid out but most of them have a description to explain what each parameter means. This goes a lot more in depth than your typical specifications you would normally find. All the values you see are estimated but most were proven after being calculated by doing test runs and measurements. If you have any questions please ask! Interesting parameters: spring rates center of gravity corner weights on each wheel max braking acceleration max driving (WOT) acceleration time to 60 mph estimated minimum stopping distance curb-to-curb steering radius NOTE: I have a fiberglass bed cap on my truck and some stuff in the back so this added about 150-175 lbs to the total weight of my truck. I am running 31" BFG tires which change ride dynamics and weight. I also have 2" coil spacers and 2" lift drop shackles. Not too much different than stock so all the values you see are pretty close to stock.
