Steeda Ecoboost Progressive Springs

[shelbywannabe]

Anyone know how these ride compared to Ecoboost Performance Pack springs ? Looking to lower the car a little but I dont want the car to ride any stiffer than it does now.
Thanks

ride stiffness is more of a function on the shocks than springs. The PP shocks on the GT are known to be underdamped so a bit bouncy and rough feeling. Aftermarket shocks were a great upgrade

I had the progressives on my old base, and now have one with the performance pkg set up. PP is a lot bouncier, the progressives were a little mushy but a softer ride. I'm not sure how the progressives would mate up with the PP shocks. Couldn't be worse than the bounciness now.

In the end I'm going to go with a linear spring instead of a progressive based on all I've read in this subsection over the last year (Mustang_Guy thread). I'll probably pair those up with a set of the new Steeda shocks/struts that just became available and have them install them. Steeda's only a couple hours away.

Have them on my car and yes it's a totally different ride, even after I upgraded to 20 inch wheels and new tires. I would recommend it for sure

I can confirm the GT pp bounce is still present with the Steeda Progressive springs when paired with the factory dampers. I also had the rest of the suspension mods in my signature installed at the same time as the springs so I can't say how the Progressive springs would feel on their own. I'm planning to pick up the Steeda shocks and struts in the next couple of weeks, the factory garbage has to go. I don't find the ride uncomfortable in any way, the bounce is just annoying, imo. Once the bounce is gone the ride will be perfect!

I couldn't tell but are you using the steeda urethane differential bushings? I installed just half of the kit(black inserts) on the rear half of the differential and noticed a dramatic decrease in rear bounce with Steeda progressives. I'm using koni rear shocks but there is still like 5% bounce there.

I skipped the differential bushings because I don't want to hear any gear whine.

The bounce has definately been reduced with my current setup, just not enough for my liking.
