Here's how I understand the suspension hinges. The suspension does not follow a straight up-and-down path. Instead it follows a curve. This curve is defined by the hinge point indirectly. It's as if the wheel itself was attached by a straight rod of some kind from the hinge point to the center of the wheel, and the hinge allows up-down movement. Take for example the front wheels, which usually have a hinge point behind them. So if the wheel moves up, since its attached to the hinge behind it, it's also going to move towards the back of the car a little along the curve. The big difficulty in this is predicting how the car will react under this movement.




ok, so i think i see how hinge works. it's L/R coord's sign is a reverse of what the associated wheel has because the actual single conceptual hinge-point is so far behind its wheel that it's literally outside of the car on the other side.

with that in mind my plan is to make a pass at the hinges of all the cars i've done thus far, and set them as such. and then resume work on teh other cars.

also, i happen to notice on my own usdm tc6's rear suspension that: as the springs compress it's wheel moves noticeably toward the rear of the car. with only 2 points involved in the suspension, i'm guessing this isn't modeled in the physics yet. is that correct? or is the 3rd point derived from the wheel position?

===========
edit, i'm noticing some strange things with some of these hinges. lots of hinges have an L/R position at 0. tc (& tc6 which i copied suspension) seem to have had their hinges originally right next to its own wheel. so virtually no suspension travel. in these cases should i try to tune each car so that the hinge is somewhere near/past the opposite side's wheel? a change like that will need to be tested a bit for each car () and might require extra changes to be made to the spring tension.

or should i just try to get the coords and signs swapped to just update each one?
