I am interested in improving my mustang 2006 GT to improve handleing, I am stationed in Panama Republic of Panama were the roads are not the best, the car has 18 inch wheels, and I am looking for suggestions to improve performance when in bumpy roads, or not the best street conditions,,,,what new suspension do you recommend?

 

eibach pro kit.

sway bar.

etc.
etc.

 

For that platform its going to take a lot. Probably a good serving of new swaybars, shocks, struts, etc...

Check out Steeda's website. They have a TON of stuff for Suspension for the new S-197 Platform.
