Hey Joest,
The diagram you posted is for a typical slider mount TA. The diagram is different for a TA with a short verticle front link. It turns into more of a 4 bar mechanism instead of a slider mechanism.

Ah hah! The traditional torque arm sliding mount has been replaced on your car by a heim jointed setup with an intermediate link. Correct? If that is the case, then the verticle line through the front mount does NOT locate the instant center for your setup. I haven't drawn up the kinematic...
The class regulations are wide open (NASA Pro Racing's Endurance Series). I am looking at tires for ~8" and ~10" wide wheels in either 17 or 18" dia. Thanks for the Avon lead, if nothing else it will give me a data point.

I was wondering if anyone on this board had any race tire test data they were willing to share. I am trying to determine how much change in suspension setup would be required to change from one race tire to another on my prototype. Since I'm still early in the design phase, I want to leave...
Did you move the whole TA up the 1 1/2"? If not then it sounds like the TA was no longer parallel to the ground in the bushing which would certainly have an effect on the line normal to the bushing axis and therefore the IC as well.
Jason S.
For a traditional TA raising or lowering the TA (at least within reason) does not really change the IC location. The reason for this is that the IC is located by drawing a line normal to the TA axis of compliance (bushing in most cases) and locating this lines intersection with the extension...
Hey guys,
I just stumbled on this great forum. I already reconize a few names from other forums, but this topic caught my interest. I'm starting a similar clean sheet of paper design for a small prototype that I intend to build and compete with in NASA's West coast endurance series.
I too...
