Difference in the GT Performance Pack Suspension Components vs No Perf. Pack

[samcrac]

I know the Peformance Pack comes with better brakes, different wheels/tires, different rear gear; but regarding the suspension what is different. I know the springs are different.

Does the standard GT have any K-Brace?
Are the both sway bars different?
Are the dampers different?

I have a 2015 GT with no performance pack and just regarding suspension components I kind of want a little more tight ride and plan on springs but don't know if its worthwhile to do dampers, sways, a k-brace etc.

I will eventually do new stickier tires. Just would be interested in getting it to the level of a Performance pack with a little lower ride height. Thanks for the help!
