The 'mountain' car is on hold, waiting for the sandblast / soda blast guy to open up his shop.
Kerry, Steve: The following is info about the cars discussed in this thread, but if you think that it is to far 'left of center' feel free to modify/delete it.
Hey Pugsy: Here is some information that might be helpful for you in making decisions about what type of suspension to use. Everything that I worked on in the race cars was independent front suspension and a rear end housing assembly retained by a pan hard rod.These 'sketches' are part of a vehicle dynamics project that I have been working on for many years and were used as guidelines for both the 'mountain' car and the narrow Talladega car.
The first three 'sketches' will be helpful in determining the center of gravity. In cornering, the G-forces will tend to make the CG rotate around the roll axis. (Fig.#19). The front and rear heights of the roll axis are determined by the roll center heights at each end. CG height/location can be determined by (Fig.#15). Front roll center height can be determined in accordance with (Fig.#16). On the solid axle/pan hard rod design, the roll center height is the center point of the pan hard rod, left to right.
This information is more dependable/useable if the frame is more stable/rigid. (Fig.#12A) is the method that I used to measure the torsional rigidity on both of the cars in this post. PM or email me if I can help.
