Give Your Launch Edition STI a Front End That Matches Its Power
The Launch Edition STI already brings AWD grip and 305 horsepower to the table, but the factory front sway bar is shared with every other WRX STI variant. The SuperPro SPRRC0099FZ-26 swaps in a 26mm hollow front bar with a 2-position adjustable end link so you can dial in turn in response to match the car's launch-ready character.
Key Features
- 26mm hollow front sway bar engineered specifically for the WRX STI chassis
- 2-position adjustable end link mounting for two distinct stiffness settings
- SPRRC0099FZ-26 bolts to factory mounting points with no drilling or cutting required
- Reduces front body roll and sharpens turn in response during hard cornering
- Complements the STI's AWD system by improving weight transfer control
- SuperPro polyurethane bushings included at all mounting points for a firmer connection than rubber

FAQ
What is the SPRRC0099FZ-26?The SPRRC0099FZ-26 is a SuperPro 26mm adjustable front sway bar kit for the 2015 Subaru WRX STI that sharpens turn in response with a 2-position end link.
Does this fit the standard WRX STI and STI Limited as well?SuperPro produces this bar across WRX STI trims for the 2015 model year, but this listing is scoped specifically to the STI Launch Edition.
What is the difference between the two end link positions?The two positions change the leverage on the bar, giving you a softer setting for daily comfort and a stiffer setting for spirited driving or track days.
Will a stiffer front bar affect the STI's AWD balance?A stiffer front bar shifts a bit more roll resistance to the front axle, which many STI owners use to fine tune the car's handling balance for track driving.
Does this bar require lowering the vehicle?No, the SPRRC0099FZ-26 bolts to the factory mounting points and works at stock ride height, and also functions normally with lowered springs or coilovers.
Do I need an alignment after installing this sway bar?No, installing a sway bar does not change suspension geometry, so an alignment is not required, though it is good practice after any suspension work.
Is this kit covered under warranty?Yes, SuperPro backs its polyurethane bushings with a lifetime warranty to the original purchaser.
Can this be installed with basic hand tools?Yes, most installers complete this swap in under two hours using basic hand tools and a jack and jack stands.
Install Instructions
- Raise and safely support the front of the vehicle on jack stands
- Remove the factory front sway bar end links and mounting bracket bolts
- Slide the factory sway bar out and remove the old rubber bushings from the mounting brackets
- Install the new SuperPro polyurethane bushings onto the 26mm SPRRC0099FZ-26 bar
- Position the new bar in place and reinstall the mounting brackets, torquing to factory specification
- Connect the end links at your chosen adjustable position
- Lower the vehicle and cycle the suspension to confirm clearance and no contact with other components
