Steeda Mustang Adjustable Competition Rear Sway Bar (2015-2026)

If you have a track or competition-built vehicle, this competition rear sway bar has been designed to meet your needs. Adjustable and with a softer rate than any of our other sway bars, this bar gives you the ability to run stiffer springs and other track-purpose parts on the car. Designed for racing. Up to 39% softer than our standard rear sway bars (555-1016), this bar works alongside your track-focused upgrades to maximize performance. The corner exit grip of your S550/S650 Mustang is increased by not lifting the inside rear tire during cornering. Engineered to work with higher spring rates, multi-adjustable shocks, and aerodynamic upgrades (wings). This bar is an excellent addition for both open track and auto-cross events. Thoroughly track-tested. Our racing teams have tested this sway bar on multiple in-house test vehicles. This goes for our Yellow #20 Race Car, HPDE 2018 Q500, Q350 EcoBoost, and more. After all our testing both on the track and autocross course, we found that with the stiffer spring rates that our competition-oriented Dual Rate Springs (555-8243, All | 555-8244, GT500) provide, a softer rear bar is necessary to promote corner exit rear grip. Relocation brackets. The included relocation brackets move the sway bar to provide greater clearance between the sway bar, other suspension parts, and brake components. Sway bar geometry is also improved by moving the bar rearward and putting the end links in a more vertical position. This increases the sway bar adjustability range, especially when pairing with adjustable end links. The more vertical position also prevents binding of the end links. End link binding can artificially and inconsistently increase the rate of the sway bar.
