The FD want to keep going straight (via inertia/1st Law of Mechanics), but when the car deviates from the straight path, the bra strap you have the FD dangling from will 'pull' it along foin a rir the ride as Bushflyr describes. Well done, sir.

Hmmmmmmmmm......what if the FD were dangling from the rear bumber tow hook......would that FD react in same way as FD dangling from rear view? Would they "sway" in unison or opposite each other? That is a very interesting question.......

Can you get FD to throw right in aright hand drift if FD are dangling from tow hook?

Because the FD are suspended the accel vector acts through the suspension point 90* to the vel vector and the inertia causes the FD to point to the outside of the curve in line with the radius.
Is that english?!?! Holy Sh*t it IS english... Damn I feel stupid... What the hell did he just say?? Yes....Josh... Can... Read...

Hard to believe. Throw may be the wrong word.

But I think I can definitely get a set of FD to go right if hanging from tow hook.

Not in a steady state, you can't.

I guess not steady state, but what happens if I make a full on auto-x style 90 degree turn? at 40 mph....but FD is now hanging from my rear bumper. same result?

So thats your original question.

I would agree with BUSHFLYR about everything said. No matter if the FD was on the front bumper, back bumper, or on a chain being dragged from behind, the fact of the matter is the FD will go left on initial entry based on weight transfer and gravity. Now throughout the drift (corner or doughnut) , the FD will SLIGHTLY come back to the right because the FD looses momentum as the speed slows down. I would think in a perfect circular doughnut, the FD will return to its normal state because of "center of gravity". But thats a totally different subject.

+1 makes no since to me going in the opposite dirrection ( scratches head and still confused )
