Specs & Features

• Choose Your Stiffness: Available in 22mm for a balanced street/canyon setup, or 24mm for aggressive track use and maximum rotation.
• Solid Steel Core: Constructed from Solid Spring Steel (not hollow tubing), providing massive torsional rigidity to keep the car flat even under heavy cornering loads.
• 3-Way Adjustable: Features 3 Adjustment Holes on the lever arms, effectively giving you three different stiffness settings in a single bar to tune your handling bias.
• Fix the Understeer: specifically designed to increase rear roll stiffness, neutralizing the factory "push" and helping the car rotate through the apex.
• Built to Last: Finished in a durable Powder Coat to resist road salt and corrosion, and includes fresh high-performance bushings for a tight, squeak-free fit.

Product Description

Subaru's are amazing, but they have a bad habit. From the factory, they are tuned to "push" (understeer) at the limit. This means when you turn the wheel hard, the front tires give up and the car wants to go straight. The COBB Tuning Adjustable Rear Sway Bar is the fix. By stiffening the rear end, you force the back tires to do more work, balancing the chassis and allowing the car to pivot around a corner rather than dragging its nose through it. It is arguably the best "bang-for-your-buck" suspension mod you can buy.

22mm vs. 24mm: Pick Your Personality Because the BRZ/86 is a lightweight RWD car, bar size matters a lot:

• The 22mm Bar: This is a significant upgrade from stock. It kills the body roll and makes the car feel neutral and sharp. It’s perfect for canyon carvers and track day enthusiasts who want grip without snapping sideways instantly.

• The 24mm Bar: This is for the drivers who want Action. If you are building a drift car or an autocross machine where you need the rear end to step out immediately, this is the bar. It creates a very lively, aggressive handling profile.

Suspension is personal. That is why COBB Tuning designed these bars with 3-Position Adjustability. By swapping the end link to a different hole, you effectively change the leverage ratio:

• Soft Setting: Keeps the rear planted for high-speed stability.

• Stiff Setting: Maximum rotation. This essentially tells the rear tires to "let go" sooner, making it easier to initiate a slide or rotate through a tight hairpin.

The COBB Rear Sway Bar is the difference between driving a car and piloting one. It removes the slop from the rear suspension and creates a direct link between the steering wheel, the throttle, and the rear tires. Whether you want to set fast lap times or burn rubber sideways, this bar gives you the control to do it.
