This is an ongoing series of articles written by its creator Bob Wright. You can download a free trial version of the software, and learn how to get the most out of your car when you take it to the track.
In the previous episode we discussed how to manipulate the front – rear weight transfer balance to adjust handling. Episode 4 will use those same tools to adjust the overall roll stiffness of the car while maintaining the weight transfer balance. The Chassis Roll Sensitivity value is the primary indicator of this suspension property. It is affected by Sprung Mass CG, roll centres, and the mechanical roll stiffness due to springs and ARB’s (Sway bars). The lower the value the quicker the car will react to inputs, be they changes in direction, bumps or anything else that may be encountered on track.
By changing the suspension roll stiffness you are affecting both the amount of chassis roll and camber angle changes so it is important to understand the impact this can have on handling.
If you wish to follow along with the demos then you can download RC3 here: http://rccrewchief.wrightdesign.ca/RcccDownload.aspx
The program will install in Trial Mode which means a few file management functions are disabled but otherwise it’s fully functional. All the on road and off road models that will be used in the demos are also preinstalled to make life easier.
