Which Track Pack?

For the money you would better off buying all of the suspension stuff from Steeda or Saleen. The Shelby GT stuff is just marginally better than stock GT stuff. My 08' Bullitt and different suspension parts from the GT, but it was hard to notice. Mostly re-valved shock/struts, and the car sat 1/2" lower, and the sway bars are supposed to be different, but it was hard to tell. There was more performance improvement from a handling standpoint by changing out the wheels and tires. I ended up with Steeda Ultra-lite springs and a few other items like different upper and lower control arms, different pan-hard bar ect. It was money well spent.

What are your thoughts on the Roush suspension package?
