With car modding the hardest part is the physics. The visual model only decides the wheelbase, everything else is just visual in terms of driving.

If you want someone to add them,and make them drive realistically. My advise is start gathering specification data and make sure all measurements are metric.

To start youd need:
-Wheelbase width and length (to setup a box chassis at the very start)
-Tire radius front/rear
-Tire width front/rear

Then you can have a basic driveable 4 wheels in game at the right size.

------------------------------------------------------------------------------
After that you need:

Front/Rear (left/right setups are not possible):
-Ride height
-Spring rates
-Geometry positioning of the suspsion setup (double wishbone) measured from hub center.
Front&rear upper/lower arms,spring,steering or trailing arm. All where they join the hub and body.

-Camber
-Toe in
-Tire+wheel mass
-Tire pressure

-Steering ratio
-Lock to lock degrees of steering

-Length/Width/Height of the shell (for moment of inertia calculation)
-Mass
-Center of mass height
-Front/rear mass distribution
-Basic aerodynamic info (front drag,front/rear downforce or lift)

-Gearbox ratios (5 max)
-Engine data (redline,idle rpm,peak power&torque,peak power&torque rpm)

Hey, I appreciate the detailed response. Let me see what data I can gather. Does the game allow RF/LF or RR/LR different size tires ?

Yes and no. The game files only support symmetrical physics. Only front/rear difference.

But they are independent in game, so you could run left/right setups if you made a 3rd party trainer.

Okay, I'll get data for the Late Models because from what I recall they have the same size tires.

I know sprint cars and all oval racing cars are supposed to be asymmetric but making them symmetric would be very cool as it would allow us to use them in all kinds of tracks, even roadcourses!

-Wheelbase width and length (to setup a box chassis at the very start)

Width:
Front: 90” - 2.286 Meters
Rear: 88” - 2.2352 Meters
Length: 104” = 2.6416m

-Tire radius front/rear

Front: 14.7” = 37.338 Centimeter
Rear: 14.7” = 37.338 Centimeter

-Tire width front/rear

Front: 11” = 27.94 Centimeter
Back: 11” = 27.94 Centimeter

I support this... this game needs it

What ever happened to this?

Nothing from my end at least. Still hoping someone makes them but realizing it's been 2 years I'm not holing my breath.

maybe if game would be able to syncronise the mods in the moment u connect to a modded server someone is willing to create mods. but as long u have to download files from unknown sources by yourself and copy files to folders by yourself it's not really userfriendly and makes mods less interesting because of mentioned issues.

Wait, what about the workshop?

does the game synconise mods of the server automaticly? i think not..

I'll be honest, I'm not sure. I don't play on any modded online servers. If it does not, that seems like a huge oversight by the devs.

All you have to do is click sub on steam workshop and then enable them in game to match the server. Some sort of auto sync would be nice, however not really practical.

Im not sure but wouldnt be surprised if you could already setup a link (to display in your server description) using steam API to automatically sub and download the required mods in the server.
