I understand exactly what is being said to me, don't mistake disagreement for a lack of understanding. No one uses camber as a tool to adjust tyre temps? Well apart from the entire motorsport industry that is. I'm not basing this on any other sim, I'm basing this on reality, and in reality camber is used to get as even as possible the tyres across the tyre face. https://nasaspeed.news/tech/wheels-...cordingly-can-pay-dividends-on-the-racetrack/ http://tentenths.com/forum/showthread.php?t=43078 https://www.elephantracing.com/tech-topics/reading-tire-temperature/ https://www.toyo.co.uk/page/index/identifier/set-up-advice https://www.joesracing.com/rt-4219-tires-temperature.html I can keep going on this one...... Now this one helps out by discussing how camber is used to ensure that a tyres maximum grip is obtained via tyre temps and also covers toe, interestingly not mentioning it as a tool for tyre temps at all. http://www.motorsportessentials.co.uk/car-setup/ Even if you are using a set value, you are still simulating it. Just to a lower level of fidelity. If you're going to use a source then please link to it, with the appropriate time code. I'm not using other sims as a benchmark, I'm using reality. Have you ever done a standing start in a FWD car? I mean full throttle and lift the clutch? You see I'm not talking about PC2, or iRacing or AC. I'm talking about the areas in which GTS differs from reality. Interestingly enough its other members who tend to throw in the 'yea but this is wrong in other sim X' any time any discussion starts about areas that GTS falls down on in terms of its physics fidelity. Its almost as if the GT series has to be treated as a sacred cow, and no bad word can be said about what could well be issues. Now part of the reason why you may feel that GTS relates well to your car when you drive it on a public road is that you will never drive you car omn a public road in teh same way you would in GT! GTS has some quite clear and demonstrable issues with what seems to be a move from a low speed tyre model to a higher speed one around the 18 to 20mph mark. However this is only apparent when you are driving in a manner you would never do on the public road. Its physics are also reasonably good below and just up to the limit, its what happens when you go over the limit, particularity with understeer when things go wrong. Now that's not a place you should be finding yourself on a public road, as such you are comparing apples to oranges. Oh and in regard to iRacing, could not agree more with you, and its the tyre model that is the main cause of the issue, it mU and Cf values are all way to low, resulting in far less available grip in all situations that I have ever come across on the road, track or proving ground. Exactly how many racing drivers have you discussed this with? I've never met a racing driver who didn't understand the impact of tyre pressures and temps, not a single one.
