Everyone has a track bar. I think you're talking about the sway bar.... which is on the other side of the axle (and i dont have one either).

The main benefit is definitely to help clearance. I've got hung up on that damn shock mount almost every time i've been to Rausch!

Flattening the outboard angle would help a bit with flex, especially as the tire is shoved into the wheel well and that angle increases which puts a lot of stress on the ends of the shocks; i think thats also one of the causes for the Bilstein shock failures that some guys had a few years ago (the ends literally broke off).

Depending on how the design works out, i bet a few mounting locations could be drilled for the shocks to help fine tune for different shock lengths. There's probably enough room for at least 2 mounting points 1" apart...
