Camber and Damping - Not Making Much Difference?

Hi all, sorry if it's been posted before, I tried the search and couldn't find anything.

So, generally I'm fairly competent at tweaking cars. Typically I tune road cars for racing tyres with a decent amount of success. I have a youtube channel where I'm making a video series aimed at helping beginners set up their cars since the tuning menu isn't all that approachable. I've got a good understanding of downforce balance, weight dist., differential tuning, ride height, natural frequency and anti roll bars.

However, I'm now at the point where I'm trying to explain how negative camber and damping ratio affects the car's handling characteristics, and I've quite honestly found very little difference.

With damping, I've tested race-tuned cars on a high natural frequency, and found that low settings make the car bouncy and unsettled more by the bumps, and other than that, there's very little effect between having a mid-to-high setting, or using higher settings at the front vs. rear or the other way around. I found it had even less effect when I tried stock cars with customisable suspension. So basically as long as Damping ratio isn't set close to or at the minimum, any other changes don't make much difference.

I then tested camber. I ran tests on blue moon bay to test performance on high speed corners with camber set to 0.0, 2.0, 4.0 and 6.0 front and rear, and the lap times were all within 2 tenths of each other. I tested at suzuka east for low-speed corners and found no difference again, and then tested multiple cars with different settings to try and find subjective differences, and all I found was that setting camber higher at the rear makes the car slightly more prone to oversteer under braking but less prone to power oversteer, and higher camber at the front makes the car slightly more agile on turn-in but more prone to power oversteer. I found this with road cars on mostly stock settings as well as race-tuned cars with mostly stiff settings.

Beyond that, I struggled to feel any real difference. Has anyone else found this or am I missing something?

I subscribed to your Youtube channel a few months back and have watched all of your tuning videos multiple times and have found them to be most informative and helpful. A former GT Sport Youtube contributor called 'WeEducateRacing' has recently been releasing GT7 suspension tuning tutorials that are excellent and easy to understand. Today he posted his camber lesson. You can find his channel here https://www.youtube.com/@TheCaptSpeaking

I hope this is what your looking for. Keeping pumping out your great videos.

^^^ I watched a few moments of some of the videos on there, and there is so much wrong it is not even funny. Ignoring things like their thinking that spring rates are psi and not lb/in, it's a complete misunderstanding of...everything. A 100lb weight on a 100lb spring does not have a natural frequency of 1. Unless the suspension has some whacky motion ratio of about .3:1 lol. On a strut car with a motion ratio of about 1, 100lbs on a 100lb/in spring is natural frequency of about 3hz. Ignoring unsprung weight, of course. Even on an SLA suspension with a motion ratio of .75, the natural frequency is still over 2hz.

A 100lb weight on a 200lb spring? Assuming a strut motion ratio of near 1:1, that isn't anywhere near 2hz. That's nearly 4.5hz. 100lb load on a 300lb/in spring? That's somewhere near 5.5hz, not the 3hz he says. Not that any of that is particularly relevant to GT7, because GT7 doesn't disclose spring rates or motion ratios, but it demonstrates a total misunderstanding of what is going on. He thinks that Mustang with a 3hz front frequency has spring rates of over 4700lb/in up front, or 3 times the weight on that axle? No. Stop.

Dude needs to stop and go read Milliken and Milliken.

I'm like wow.

Stay off youtube, kids. Library cards are free.
