GTR: You must be kidding me

>> Thats 'Sideways Stephan' and he does it just for show on the RUF videos That explains it. > Sideways is never fast. If the tires are at that slip angle, > they ain't developing max cornering force, for sure. If you look at actual lateral force versus slip angles there's not much, if any loss in laterforce at higher slip angles, except for the fact that tires get overheated. Avon is one company that publishes this data, and Todd Watson, who has been working on basic simulator physics, has done a lot of research on this consulting experts, and there's little loss of grip at higher slip angles, it's just the lateral force is not quite in the right direction. It also depends on tire contruction. IRL (Indy) cars have the smallest "working slip" angle of about 2 degrees. F1 and Cart cars are more like 2.5 to 3 degrees. Most non-downforce racing cars wihtout tire restrictions will use bias ply slicks, with a slip angle around 4 to 5 degrees. > If the GTR cars weren't a lot less forgiving than GPL cars Yes I agree with this, I feel that some aspects should be compromised to make up for the lack of feedback. Traction control is one way, and realistic, since it's used in FIA's F1 and GT1 classes. Champ cars don't use traction control, but looking at videos of events at Laguna Seca and Brands Hatch, there are a lot more incidents than in F1, maybe fun for the spectators, but not the drivers and teams. |

GTR: You must be kidding me
Getting back on topic. I still haven't seen an explanation
for why driver induced understeer barely works at all in GTR. If GTR's physics model is implemented so that lateral force is reduced at excessively high slip angles, then why doesn't pegging the steering wheel induce a large amount of understeer? Somethings up with the physics. I've tested this in real life on a Trans-Am (front weight bias car), and a Caterham (rear weight bias car), and it works well on both cars. In addition, I've seen posts about this method being used by many club and professional racers. |
