Let's put it this way. I have absolutley no doubt the GT3RS is faster on the track than a GT3.
In the same test which I refered to in my first post the laptimes on the Nürburgring and Hockenheim for the cars were:
GT3RS: Nürburgring 7:33; Hockenheim 1:09,6
GT3: Nürburgring 7:40; Hockenheim 1:10,4
All I'm saying is I don't think the downforce makes THAT much of a difference. After all the RS has 15hp more and weighs 30kg less. Also it has bigger tires and an increased front width.
I just don't think the downforce is to thank for the better laptimes more than any of the above named improvements compared to a "standard" GT3. I'm not saying more downforce doesn't help, I'm just putting it into perspective.

^Both our points are valid. I want maximum speed. If I didn't, I could go fast in a 1999 Boxster. Plus, I think wings are cool. Can't argue that one.

How can you have downforce at rest?

^ I'd disagree with both of you on the wing issue and say the standard GT3 .1/.2 wing is MAX but then you would round up FredSF and all wage e-war on me.

Based on this question, you must have become predisposed by your GF after yelling "oh f**k me" while looking at the GT3 threads, as you forgot newton's law of physics. I just hope you had a good time.

While all of that is true (and yes I did.. have a good time.. twice) I still don't understand at rest (no speed, right?) you can have downforce. Wouldn't that just be the weight of the car? It's at speed where cars start to float, and the wing position directs the air to push the car down. So my understanding is that the same wing will create different amount of downforce at different speeds, with 0mph = 0 downforce. More speed = more air going over = more force pushing down on the wing.
Probably wrong, it's happened before, but please enlighten me on the physics. This Law stuff is getting me down.

You are completely right. I am just jacking with you. We were actually using downforce and weight as being the same thing. Really they aren't, but to an extent they are. There is downforce at rest, but it is only weight (gravity). When at speed, you get downforce from air, but you lose downforce from the weight. In any scenario, you get a combination of pressure on the tires that can be a combination of weight, air pushing, or even lateral when cornering. Therefore, a wing increases the pressure downward on the car and allows extra speed in corners.

Ok, I know this is common sense. I just typed it up. Sorry.

No no, not common sense and you had me scared with my understanding so I appreciate your confirmation. We are on the same page again.
As you lose weight's force with speed, you gain down force from the air with a wing.
