LOL. You talk about wikipedia and yet thats probably where you got that info. LOL.

I have never talked about racing ( real life racing and specs ) with anyone on this site. So your pulling accusations out of your backside. I have only ever talked about the Racing in VIDEO GAMES on this site. And now you bring to attention all the stuff you dont understand, it's a perfect oppurtunity to say to you that is exactly why Forza is leagues ahead of GT. Forza has so much more tuning options than GT it isn't funny. Yes I only have GT5P as a guage. But Forza 2 wiped the floor with GT5P in terms of tuning. After playing Forza 2 then playing GT5P not being able to to set variable camber on GT5P for instance is painful. Yes you can change camber, but it's so basic compared to Forza 2's dynamic variable system it hurts.

The fact that you think GT has been at the forefront in Realism proves to me that you know very little about racing, and what actually affects the car as it hurtles through a corner at 100 mph.

The majority of things you talk about there are mechanical and only influeantual in certain racing competitions. Almost all racing competitions have a certain spec list to operate to. Meaning you have to opt for a certain LSD or you will be disqualified. Competitions have rules. Many things affect the handling of a car. The reason why I mention Tyre deformation so much is that the tyre on any car in any competition does 60% of the work for handling. That is the only part of a car the touches the road. It converts the power, the braking, the entry and exit speeds. Also the brake temperature affects the tyre temperature. A track may be 30% and be optimal for one type of tyre. For instance softer compound will heat up faster and have much better grip quicker. But fall away much faster as they grain. Forza 3 has all of this implemented. Again this then affects understeer and oversteer. But another driver may be on a harder compound. Which will take longer to heat, but provide better grip for longer. Even then it depends on a cars aero design. Certain cars can make softer compounds last longer because they treat cars tyres better in the corners.

Tyres and their condition can make as much as 4 secs a lap in race conditions. If GT5 does not have this very intricate system ( which takes alot of resources to calculate ) then it's fail fail fail in terms of realism.

I'm referring to how a car behaves. Car behaviour >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> looks of the game. Because if night racing is implemented. You then have the track cooling down. Maybe from 30 to 18. This agian makes the handling of a car change completely. Braking zones change, accelerating changes as does race lines. It's not like you can just implement something like night racing unless you can replicate the changes realistically. Night Racing isn't just about it going dark. It changes your driving completely.

That doesn't change the fact that having no night time racing in a Le Mans 24 hour race = fail fail fail fail in terms of realism.
