Hey all I have a ‘21 Mach 1 with handling package parts and some aftermarket parts for better alignment. I do maybe 4-8 track days a year and run 200TW 305’s square. For my purposes I need to keep at or close to factory ride height and good ride while keeping the dust boot (I drive on some roads where I don’t want the shaft exposed). I’m running HP rear springs (742) and GT500 CFTP front springs (268) that I just mounted on the struts. I haven’t installed the struts yet so this a prime time to upgrade the front sway bar. I just so happen to have a Steeda front bar, but the factory Mach 1 bar is a bonded bushing bar. I’ve heard this is to help on center feel, but I’ve also heard it is to help add spring rate in bump (bonded so there is resistance not just in roll). Would it be a bad idea to ditch the factory bonded bar when running soft/compromised front springs? Obviously the steeda bar would greatly increase roll stiffness in the front, but would I miss the added rate? Right now it’s easy to swap bars since struts are out.

With the factory HP setup I felt the car a little too loose, including some corner entry oversteer. I could drive around this, but I feel it could be better.
