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.
