Frequently Asked Questions

What does RC0013FZ-22 replace on the WRX STI?
The RC0013FZ-22 replaces the factory front sway bar on 2011-2014 Subaru Impreza WRX and WRX STI models, delivering a stiffer, more responsive bar for improved handling.

Will this fit a 2008 WRX STI?
The RC0013FZ-22 fitment starts at the 2011 model year for the Impreza WRX/STI platform. For 2009-2010 Forester XT models this bar is also compatible.

How do I choose between the soft and firm settings?
The inner (soft) position delivers milder body roll reduction for everyday street driving. The outer (firm) position maximizes stiffness by up to 50% over factory for autocross or track use.

Will installing this sway bar void my Subaru powertrain warranty under the Magnuson-Moss Warranty Act?
The Magnuson-Moss Warranty Act protects consumers; a dealer cannot void your warranty for an aftermarket sway bar installation unless they can demonstrate that the bar directly caused a specific warranty claim failure.

Is wheel alignment required after installing the RC0013FZ-22?
Yes. SuperPro recommends a four-wheel alignment after any sway bar installation to confirm that suspension geometry is within specification.

What tools are required for installation?
Basic hand tools, a torque wrench, and access to a lift or jack stands. No special tooling is required.

How long is the warranty on the RC0013FZ-22?
The metal bar is covered for 3 years or 37,282 miles from the date of purchase. Polyurethane bushings carry a lifetime warranty.

Does this bar produce more road noise or vibration compared to stock?
No. SuperPro polyurethane bushings are engineered to provide a firm but compliant interface that minimizes NVH increases compared to rubber alternatives.

Installation Instructions

  1. Safely raise and support the vehicle on jack stands or a lift.
  2. Remove the factory front sway bar end links on both sides.
  3. Remove the factory front sway bar mounting brackets and sway bar.
  4. Lubricate the polyurethane D-bushings with the included Slippery Stuff grease.
  5. Slide the D-bushings onto the RC0013FZ-22 bar at the correct mounting positions.
  6. Position the bar into place and install the mounting brackets; torque to specification.
  7. Attach the end links at the desired adjustment position and torque all fasteners.
  8. Lower the vehicle and perform a four-wheel alignment.
