Questions about origins of Roush Suspension Parts

[wms004]

So the Roush claims slightly over a G on the skidpad with its suspension setup.. I doubt roush makes all their parts, so where do they come from? I'm guessing the dampers are bilstein.. how bout the LCA's

and the swaybar

and also the springs.. anyone know the spring rates front and rear?
Lastly a little off topic, but would this be a good alternative to the expensive C&L metal trueflow inlet pipe?

.. only 55 bucks

thanks for any input

Don't forget the tires too. Those alone could help transform a car.
