Thought a preview of the new suspension Dynamics feature that's in work would be appropriate. Still have some work to do but you should get the idea.

I've included a screenshot and a link to a quick Youtube screen cast video.

Setup Print (just for you)
On Handling page allow suspension link positions and shock positions (similar to setup page) to be changed.
Add option to save changes made on the Handling page back to the setup.

Hope to have this update out in a week or so. Then I will start working on modelling the droop settings.

The multi-level shock mount points involves significant changes to the database structure so will likely not happen until a major update.
Do you have a list somewhere of the chassis you have in the program?

The website FAQ page has a list of the currently available chassis. As new chassis models are developed they will be added to the download page so you can add the ones you want to the program database.

You can also create your own models if you can wield a pair of digital calipers.

Bob, I downloaded the demo but haven't had a chance to check it out yet. Are you able to model oval cars that are asymmetrical?

Sorry pan/oval cars are not supported. Only symmetric independent suspensions.

These aren't pan cars. They're buggy based (B3, B4) dirt oval cars. Great job on the program!

love the print option Bob really handy with the nitro car being usually there is no electric and my antique laptop dies quick i run off the base i leave with and then one biased in each direction to test against with at the track still trying to get that BMI Chassis to work outside on rubber thought it would make a great drift car

ok I have saved my basic setup and can see why im graining my left front on my current setup, there is a huge circle on the left front, under braking or corner entry, my question is - would stiffening the roll or raising the roll centers and running softer springs help ?

this is not something i have tried on track yet

If you have graining on the front left I assume your car is pushing (under steering)? If that is the case then so you need to tighten up the front or free up the rear of the car. That will mean either softening the front, or stiffen the rear or possibly a combination of both.

The handling page will always show a large circle on the front left on corner entry since that is where most of the weight is moving. Look at mid corner where you are just turning (lateral G only) and if there is a big difference in the wheel loads on the left side then there may be to big a difference in front/rear roll stiffness or roll centre locations.

Before you start making changes go back to the Setup Page and look at the roll stiffness values. Since TC’s are generally well balanced the total roll stiffness (combined spring and ARB) values front-rear should be fairly close. If they differ by more than 20% then you likely want to bring them closer together. Shock angle changes are good for fine adjustments. Use Spring rate & ARB for larger changes.

I would suggest just making one change to start and then hit the track to see if that has helped.

Generally I find a good place to start is with the mid corner setup neutral (bar graph in the middle). Then you can decide which way to move the handling from there.

If you can export the chassis file, email it to me and I'll have a look. If that doesn't work then just send me the numbers for the rear suspension and I'll input them here so I can see what the problem is.

I won't respond to your pm now.
