I was just wondering if any one here has fabed up any part of there rear suspension? i.e rear control arms, panhard bar, torque arm, if so I would to know where you got your designs.

 

More than likely they looked at the designs of others(companies) and changed them a bit to suit any other needs they have such as exhaust routing or... well, that's about the only reason you would need to change anything on the suspension. Possibly to make it stronger. I.E. thicker/different materials.

 

check the fabrication board, many have done that sort of thing.
