Questions that Need to be Answered

First:
Where can i find the aerodynamic kit for the GT. I've seen a GT kit on a notchback and it looks pretty good. I'd like to know where i can find this kit.

Second:
What is a torque convertor, and a stall convertor? What are their functions and what does it do in correlation to performance?

Third:
What are traction bars and lift bars, I've heard they replace the control arm setup, is this true? And what is good for performance because i've seen a number of vehicles with either setup.

Fourth:
Does anyone know how the Strange Engineering shocks and struts do compared to the Tokico or Koni brand? They seem cheap for the adjustbility function.

Any insight would be appreciated. Thanks!!
