    Very Good Rear Sway Bar

    This sway bar is very easy to install. It has significantly improved the cornering of my Mustang GT 2016. Steeda manufactures great components that enhances the cornering of the S550. In addition to the sway bars from Steeda, I have also installed their Subframe Brace Kit and Steeda Extreme G-Trac K-Member Brace.

    Race car worthy!

    I had a local shop do the install in order to avoid any potential headaches. During the install, I also had them do all of the other potential suspension mods (Front Sway bar, New shocks and struts, linear springs, Rear IRS Subframe Support Braces, Vertical Links, Rear Toe Links, etc..). Due to this, it's hard to tell exactly what did what in terms of handling. All I know is that my car now handles like an absolute track car that is leaps and bounds beyond the already awesome Performance Pack offered by Ford for our cars (which is what my car used to have equipped). Due to all of these mods, I can now take corners at easily over double the speed that I used to. Canyon carving has become a much less scary and intense dream, as my car is absolutely planted to the pavement. Even better yet, the daily driving was by no means compromised, as the drivability is close to stock feeling (aside from being able to feel bumps more). But again, I think this is thanks to all of my suspension parts working in perfect harmony with one another.

    Worth every penny!

    I purchased both the front and rear sway bars. I installed just the rear and took it out for a spin and man that alone made a huge difference! I wouldn't recommend putting on the highest setting though... The middle ground for both worked just fine. Man you won't be disappointed!
