Caster

[anasasisxenophontis]

How much would you typically use on a sand car? There's very few that have noticable caster from the pictures I've seen on this site. What are the benefits/drawbacks?

More, the straighter it will naturally go, but at the same time be harder to turn, less make for a "loose" ride...

Before I tell you that you are wrong, tell us what caster is.

BTW, The angle the kingpin makes with Vertical....Generally the top is towards the rear of the car "Posative caster" for more straight line stability....

It depends on the car, weight, setup etc. I would keep adding until you feel that it is wearing you out, then back it off, unless you want loose steering. You will most likely end up between 6-10 degrees.

If you are going to do a lot of fast long distance runs then you can go with a lot of caster. If you are going to do a lot of turning at slower speeds then use less caster. I use 5 deg of caster for trail riding.

My car is set up at 8 as well as two freinds cars. I was always told to go with 8 cause its a happy medium.

I run 14-15 because I like the stability over 60 mph and it still steers thru the bowls fine I also use a motorcycle steering damper(adjustable) because I'm usually following these big 4 seat tanks and it eliminates most of the feedback from those deep ruts

Ok, I'm getting a little confused here. I thought I had grasped the concept, but plkracer mentioned adding caster...how is this done?
I'm looking at a picture here, I hope yoshi doesn't mind me referencing one of his cars.

On that car, the angle of attack on the a-arms is tilted back a bit so that they are not parallel with the ground. Is that caster? If not, what is that called? And what does it do to benefit driving... I've noticed only the faster, more aggressive cars use that tilted angle of attack...is it a performance thing?
