So, I've been making cars for a while now, I have used double wishbone and single wishbone for all that time, but when I see people like Amplar's or Pringle's cars, they run so smooth. Even when I use thrusters, my car bumps around at high speed and swerves off at higher speed. I noticed these cars have a low gravity looking system. Would anybody be willing to post a video or picture explaining this amazingly smooth suspension to me? I'm aware of the variations like Live Axel and the like, just give me the best one for speedy off-road buggies. Any help would be appreciated.
use low damping
say you have a 50,000 constant, try around 700-900 damping and relative damping. it allows the suspension to move quicker.
[editline]22nd January 2011[/editline]
so the ratio of constant to damping should ideally be around 70:1.

Those are the exact settings I use.
A massive body weight and super-soft springs is how old american cars had great ride quality. To my knowledge, this is how others do it as well--lots of travel, comically soft elastics.

some people add heavy nograv props too
I was wanting to ask this question so what does relative damping do?

Terrible things..
I don't actually know now that you mention it. I usually leave that on 500 and most of my vehicles were 20,000 2,000 500 with multiple (usually 2-3 per wheel)
Now that Wire Hydro's have the Constant, dampening and length all adjustable I just use those. Great for heavy loads and tweaking. You can even just use a few advanced inputs and modify as its driving around.

but remember that gmod cars cant go fast without bouncing a little
if the suspension can move fast enough it can absorb wheel bouncing
Thanks Amplar, my car doesn't skid off at high speed or bump nearly as bad, I'm still a bit curious about nogravving some props.
ive never ever nogravved props on anything
When i'm making suspension, i'm always doing the suspension that Zeos do.

Take a prop. Welded it under your car. Nograv it.
It just increases the resistance to inertia of the body...like making it that much heavier, but you can still use soft elastics. Downside is the car then tends to float even on wheel power (I use karb's wheel hacks all the time anyway, so I don't have this problem)
Some people now use wire hydraulics to make suspensions, I use them occasionally for trucks as they have the advantage that you can actively adjust the height, dampen the ride, and hold more weight.

Anywhere I could find these wheel hacks?
On a slightly-related note, When my car hits a bump at high speed the wheels sometimes fold upwards, any way to stop this?
Take your limiter rope, put it halfway along where you want the suspension to travel (like 1/3 of the way up your elastic's path). This way it stops the wheel before the elastic is 100% compressed.
I show an example on my track tutorial, it's a double-radius limiter.

Now it just veers off to one side when moving at speed.

Your rope limiter is in a bad spot. It needs to go someplace "special" everytime you build a different vehicle. You just have to know where that place is.

Hrm.. I find that mostly cheat (59% to be precise). I mean essentially you could drive up walls and along the ceiling with that. I guess in certain cases that can make sense. Did you use Jeeptire on that beforehand?
and gobs of weight!

Odd I would post that particular contraption here as it has no "real" suspension. It just rocks the front and rear axles off the body.
What do you mean by real suspension? That contraption you posted looks to have suspension by the fact the tires can move vertically up and down, it looks stable as well. Look at the half life 2 jeep, the suspension movement looks similar to that contraption.
Anyone can inform me? I don't think I know what a rope limiter is. is it a rope you place so you stop the wheels falling completely to the ground if there is no elastics? I not sure.
[QUOTE=Toyokunari;27660040]What do you mean by real suspension? That contraption you posted looks to have suspension by the fact the tires can move vertically up and down[/QUOTE]
Yes, individually left and right they can move but if I were to hit both into a curb at the same time there would be no movement of the tires Vs the frame of the car to absorb the impact and your spine would shatter. For it to really be a suspension it has to be able to move the left, right and both wheels independently of the body.

Most suspensions in real life have their travel limited by the shocks. If you pick up a real car the tires go down a few inches then stop. But in Gmod elastics can be pulled infinitely. Ropes cannot. So you add an invisible rope to stop the suspension from traveling downward (or upward) any more then it should.
if you hate the sound of the wheels, you can magnetize them to eliminate almost all collision noise :v:

that's neat, never knew that. for years I had replaced the rubber smack sounds with blank ones.

do you know where/how I can get blank sound files? Now that I'm building so many ground based contraptions the rubber smack is getting really annoying.
