Cars GT86 CG_LOCATION=0.575 ???

[ifkorf]

I was poking around the suspensions.ini file for the Toyota GT86, and was a little shocked to find that the CG_LOCATION value was 0.575. The line comment suggests this is the F/R bias. However, the press literature indicates 53/47. Does CG_LOCATION interact with other variables, or is the ks_toyota_gt86 really this far off?

Hub masses affect the overall corner weights, which is what generally gets reported.

That's not really the answer I think. The NA Miata is 51.5, which is about right. Perhaps with fuel it balances more towards 53/47?

Miata might be wrong in that case

Here's a list of official cars sorted by front weight bias. I'm only showing those with 50% or more on the front. As you can see, the gt86 is an outlier among FR vehicles. Never mind the "cars/" prefix. I scripted this and that was an alias to the install directory.

Yes and? I told you what other information goes into the actual corner weights. If that's different from car to car, sorting that list means nothing.

The Car Physics dev app shows that balance is highly dependent on fuel load. It goes from 56.1 to 54.5, from empty tank to full. It doesn't get to 53/47 though, and there's no suspension height to change.

The CG location is only related where's the engine is (front, center, rear) and it change the CG 0.60 to 0.45.
Most of the car have front engine so you can expect a 60/40 (60% on front/ 40% rear).
Race car is around 50/50 or 55/45 (they place the engine in the middle of the car).

But changing CG will affect all the physic (position of rims, suspensions ...)

EDIT : i mean when manufacturer talk about CG (60/40...) they refeer to the engine position.

not only the engine position, but the engine position had a big role on CG which means the weight distribution of a car.
