WebAs with mechanical trail, pneumatic trail exerts a torque on the steering that tends to make it return to the central position. The faster the car is travelling round a curve, the greater the restoring force, and this provides useful feedback for the driver. WebAug 26, 2024 · Trail is a bit more complex. It's a fairly important part of being able to detect where the tire is on its curve of lateral force vs slip angle. Too much trail and the car feels too linear (as you drive off through the sandtrap), too little and you lose all force feedback as you approach max latacc.

WebJun 14, 2014 · You would like to have steering feel that makes it stupid easy for the driver to feel out the limit of the tires - doesn't mean it's possible. Beyond that, the steering system (and feel) of a modern car is much more involved than just pneumatic and mechanical trail. You could do a whole Masters or PhD thesis on it (and I know guys who have). WebDec 4, 2024 · The image below shows what pneumatic (labelled Tire Self Align Torque) and mechanical trail do in the real world, the result of which is what you feel at the wheel. In game, the same thing happens. If you reduce the mechanical trail, the overall alignment torque is reduced, and the “peaky” aspect of the pneumatic trail only will get exposed.
