bullitt suspension

whats the difference between the mach 1 and bullitt suspension. I have the bullitt suspension in my GT and love it. The only complaint is the rear sits a little lower than the front. I wish the front was just a little lower. As far as handling its much improved, while not too radical.

The bullitt includes
-Upgrades Shocks and struts (tokicos)
-New springs (650 linear fronts, 250 progressive rears)
-Stiffer swaybars, although the rear is smaller than the GT's I guess its solid where the GT's rear is hollow.
No complaints though, its very neutral. Although it rides a bit stiffer, but thats expected in an upgraded suspension. I believe all those numbers are accurate.

Can anyone compare the mach 1 suspension to that?
