Hello
I'm new here, but I am very impressed by your suspension research in GT6. It's great that someone finally tried to explain how it works based on in-game coding. However I'd like to ask You a few questions:
1.

This is very interesting, and I can confirm that it's true based on testing, that I've been doing for past two months. Question I have is: how much fixed dampers and anti roll bars on stock suspension setting differ from the adjustable ones, let's say set to 1 (bound, rebound, and stabilizers)? Like average?
2. Are You really sure the toe angle, that we set in GT6 is individual for each wheel, not total? I'm asking this, because the in-game visible toe (while watching replays for example) looks more like the setting is rather for both wheels (I think). I haven't graphically measured it, but it may be possible.
3. You've established that spring rate is connected directly to the weight of the car, more specifically to the weight distribution and axle weight. I can also confirm that. When lowering front spring rate to the minimum, many cars will touch the ground during hard braking and steering at the same time. Also often wheels are touching or even penetrating the wheel arches (visible in Alfa MiTo for example). However I'd like to ask You about the calculations, and how You see them. For example:
1970 Dodge Challenger R/T 426 HEMI. Curb Weight: 1724kg. Weight Distribution: 50/50. Spring Rates F: 4,79kgf/mm R: 3.86kgf/mm
So the weight distribution is 862kg/862kg (that's quite off for a big block muscle car, but on that later on). If I change weight distribution to 55/45, maintaining the actual curb weight it will be around 948kg/776kg. Then how to calculate spring rates to make them match weight distribution?
4. Curb weight and weight distribution. That's the part where I don't agree with You 100%. In many cars in GT6, weight distribution is so much off the real values, that it can't be explained by the weight of both the driver and the gas tank. For example Ford Focus RS, which has 50/50, Callaway C12 (59/41), VW Scirocco R (53/47) and the list goes on... So maybe the weight distribution i deliberately wrong to maintain certain cars behaviour realistic? Or is it just a mistake in numbers, how do You think?
5. That's a bit different topic, but have You spotted, that many cars in GT6 have a standard fitted LSD, where in real life they haven't? Lotus Esprit was never fitted with LSD in factory for example, same goes with Alfa GT, Renault Megane Coupe 2.0 and many others, especially european cars.
Anyway, thanks for this research very much, it confirms many things i suspected in GT6
