Mid Travel

What would the wheel BS have to do with travel?

 

Yeah....the wheels dont have any impact on suspension travel.

 

No it wont. Its not lengthening the arms, wich would in turn increase "travel". Regardless of the BS, it will still only go up and down what the suspension components will allow. If you had a BS of -14 feet, the tire would still go up and down whatever amount the suspension will allow.

 

I see what your saying, but the wheel is fixed to the hub. The hub goes up and down 8" (random number), and when the tire is attached, it too goes up and down 8"....Regardless of the back space.

 

Nope. The wheel moves along the same plane the spindle does. Longer CA's = more travel. More BS = no more travel. You can have a wheel 19 feet past the hub, its still gonna go up and down only the 8" the suspension allows. If the wheels moved up and down in an Arc, then Yes. More BS would give a little more travel. But, with a double "wishbone" suspension, the wheel travels straight up and down (for the most part), and follows the movement of the spindle. Now, at extreme droop, the edge of the wheel actually goes UP a little bit, as the Camber goes into the negatives to the tune of about 3*, and twards the extreme compression, it goes into posative about 2*, but thats because the Tacoma doesnt use a parallel CA set up. As the suspension droops, the angle of the UCA is at a much steeper angle than the LCA, thus pulling the top of the spindle in a little more. Then on compression, the oposite happens.

 

Your arm is connected at one pivot point, and moves in an arc. The Tacoma (and many other vehicles) use CA's to connect the spindle at an upper, and a lower location. They then mount to the spindle in the same respective points. This allows the spindle to move in a vertical plane, while remaining straight up, and not moving in an arc.
