You still appear fixed in the view that if you don�t see a squat then there isn�t a force there
Not true. I never said that. I was very careful not to.
Obviously there is a force at play there, otherwise there would be nothing to compress the rear springs. My focus is the additional effect created when the springs are compressed further and there is more downward travel of the rear of the vehicle.
About what you said about at 15degress you only get 3percent CoG closer to the rear wheels, that's a lot and don't forget that during the squat the rear end also accelerates downwards (travel) with this extra weight. If your starting to concede that it does work but the effects are not significant then you need to remember that all drag racers do every small mod that they can to get every incremental improvement including dumping the exhaust etc.
Just had a quick squiz at the link you gave, bloody good find mate
He describes the physics of weight transfer in a very simplistic way, but not sure if ge goes on later to describe how suspension plays a part in enhancing it (don't think do), although he does hint with factors such as height etc. The model he uses probably assumes firm suspension all around. His description focus is based on moment of inertia through the centre of gravity through an accelerating/de-accelerating mass, I have no arguement with that.
When I get time to sit down undistracted at home after work I want to read through all the chapters on that site, but at this stage, I haven't seen anything he has written that contradicts what I was saying before, rather, he may have written a few things that has contradicted what you were saying regarding weight transfer and Centre of Gravity, but I'm gonna have to read it properly, I'm at work now.
In the mean time I have one small point to make, just because he doesn't factor into it the effects of suspension setup and how that enhances the weight transfer, that doesn't mean it doesn't exist. In that article he was describing what weight transfer is in the simplest manner he could without making it more complex by adding extra factors into it.
Once again, excellent find! I was trying for ages to find info like that. I was starting to think that I was going to have to pull out the old uni text books and do it myself.
I need to get more savvy with the search engines.
By the way, I've found this similar debate in forums all over the world, all of them with very little or no resolution, so this thread seems to be doing ok, at least it's deriving an answer.
