hmmm thats a good question...

1. metal, if they saved 2 lbs on each arm, 4lbs for each car, multiply by 100,000 cars thats 400,000 lbs of metal saved.

2. in my eyes the upper arm just keeps the spindle straight and the lower arm takes all the punishment,

3. the lower arm has the torsion bar connected to it.

4. upper sits on the side of the frame rail, lower sits under it

the exact reason why it is shorter is unknown to me, i dont know what exact benefit that apply's. To me it seems right to make it longer, i dont know why, it just looks and sounds better to make it longer and stronger.
