A double wishbone setup is described as only that; 2x A-shaped arms. They provide horizontal support and allow controlled camber through the suspension travel, as well as allowing the pivot point to be located far enough away from the spindle that it reduces torsional issues. This game doesn't have any application for a double wishbone, but it does have use for a 4-link setup and a linkage setup (though tuning and geometry are very difficult to pinpoint on linkages).

Depending on the design, double wishbone, 4-link, and linkage setups all allow a rising rate suspension setup.

The largest bnefit with a linkage is that it can allow a smaller package and still provide sufficient travel, even with a much smaller shock. The rising rate property is also another huge benefit as it provides great deals of both comfort and bottom out resistance instead of one or the other. When combined with a multpile rate shock, the effect is even greater. They do require a specific valving for each setup before they caneven begin to function properly.

THAT is where this game falls behind. I would absolutely love to see the ability to adjust rebound and compression. That is why the majority of my ideas are held back.


Back on topic...

The idea is great if you plan on using a variable rate setup. If not, I see absolutely no need for it.

Some of my cars since I did the first tutorials:

OP was drunk. All is forgiven.

DCR3D definately needs progressive rate shocks. These would be the best way to get a smooth ride.

I'd love to see a full-fledged suspension setup in DCR3D. It would be the first of it's kind and I'd be a very dedicated customer. I have a pretty extensive knowledge in suspension and would be willing to help as much as I could.

The answer would be pro-link... but the frame material is too flimsy. :x

You mean like the Honda Powersports Pro-Link? The TRX250R comes to mind. Just sold one a few weeks back.

Yep, I have tried different configurations, but It puts the frame material under too much stress and the result is a bouncy ride.

I did try a linkage nearly identical to the TRX250R used in conjunction with a direct-mount shock on the rear to try and reduce bottom out. The link was largely unused until the majority of the travel was used up, at which point the shock pressure came on like a lightswitch. It was hard to bottom out, but rebounded like crazy. Even with the engines placed in the rear and the driver moved rearward, it was a handful.

Jeez at some of the stuff that I DON'T publish lol.
