i disagree and think absolute downforce contribute more to any sideforces but this depending on tyre performance. on ice, side forces would be much better than downforce but on stickly slicks or high performance tyres...the same rule does not apply
lets take f1, suzuka, 130-r corner, recorded at more than 5g to 6g yet downforce during that corner is not 4 times greater that the vehicles total mass. now lets assume an f1 car can do 3g on corners without downforce...for side force to achieve those g-forces at suzuka's 130-r, it needs 1500kg, say if the cars total weight is 750kg. so when we take a transient look into this, as the wing tilts towards sideforces from downforce...it will loose downforce...and logically it will lose grip and those advantages....
again on ice, however, i would take side forces anyday
All you've demonstrated is that aero force parallel to the road would be less effective than aero force normal to the road within the limits of your scenario. This is true, but it leaves out the whole question of this thread which is to determine the optimal intermediate angle.
Your reasoning would be valid if we knew for sure that the progression in DF from a parallel to normal force vector was linear, but we don't know that. In fact it turns out the progression is sinusoidal, which means it may have a peak in between those two end points. And it does indeed have a different peak.
FWIW this is the same invalid argument that supports libertarian politics; since unfettered capitalism is better than unfettered communism (we imagine - no one has ever tried either) that means we must have unfettered capitalism as is no intermediate point could potentially serve us better (even though every society that esisted always sat somewhere in the middle of the spectrum rather than at any end point)
But that's a topic for a different thread.
