I am making an APC and I would like to have working suspension. I make the base (Made of light cardboard), put squares under it where the wheels connect to, and then I fill the gap between the wheel peice and the body with springs. I put the springs on strength 10 and stiff and I even put 2 springs per joint, but when I get in the vehicle and drive it, the wheels grind into the body and the springs sink down way to far. Why can't 6 springs (3 wheels, 2 per wheel) hold up a hollow cardboard box?

i find that the squares need to be metel or stone to work.that is what i use and it works fine. just try out difrent things then you can turn the base to wood so it does not go away if it gets hit by a bomb.

The problem here is not the springs but rather what the springs are connected to. There is a direct correlation between connector strength and mass of the objects it's connected to. Your cardboard car body is likely not the problem. Being large, it will likely have enough mass to support your suspension. My guess is that the squares your wheels are connected to are too small and/or too light. As bikerider suggested, turn them to stone to increase their mass, and make them as large as you can. You fill find your springs a lot more springy this way and will resist twisting and breaking.

Thegide pretty much summed a lot of things up. But if you still have problems please be very specific with the materials and statistics for each connector (strenth, length etc). Generally, your car material doesn't matter as long as it's not too heavy, the bottom of the car (or in other words, whatever the tops of the springs are attached too) should be wood or metal, the back of the wheels (or likewise, whatever the bottoms of the springs are attached too) should be metal or wood too. (All this is general.) If you want me to go into really complex forms of connector suspension, different combinations of spring with other connectors (such as springs w/ pistons or springs w/ elastic) actually give very different effects.

Yeah, I changed it to metal and now it works. Thanks!

I guess I'm late to the party but I still wanted to chime in. If you want to see an example of an independent 4 wheel suspension, I have a demo/giveaway level that showcases one. It's called "4wd buggy with independent wheel suspension."
