Whiteline 22mm 3 Point Adjustable Rear Sway Bar – 2022-2025 Subaru WRX

Description:

Whiteline 22mm 3-Point Adjustable Rear Sway Bar - 2022-2025 Subaru WRX

Three Positions of Rear Roll Stiffness Tuning for the VB WRX
The Whiteline BSR57Z 22mm 3-point adjustable rear sway bar for the 2022-2025 Subaru WRX gives VB owners three distinct rear anti-roll stiffness settings to dial in the handling balance for their driving style and application. The factory rear bar is significantly softer -- this bar provides a meaningful upgrade across all three positions, with the range covering spirited street use through committed track driving. Hollow chromoly construction provides high stiffness at a competitive weight.

DETAILS

• 22mm 3-point adjustable rear sway bar for 2022-2025 Subaru WRX (VB chassis)
• 3 adjustment positions for fine-tuned rear roll stiffness control
• Hollow chromoly steel construction
• Includes rear mount bushings and hardware for complete installation
• Direct replacement -- VB-specific fitment confirmed
• Significant rear anti-roll upgrade over OEM

Three Positions -- More Tuning Flexibility
Three adjustment positions give more range than a typical 2-position bar. Position 1 (inner, softest) is appropriate for street driving and light track use -- meaningfully stiffer than stock but not harsh. Position 2 (middle) is the balanced street/track setting that most VB WRX owners run as their default. Position 3 (outer, stiffest) is for dedicated track use and autocross where maximum rear anti-roll is the priority.

Matching the BSF51Z Front Bar
The BSF51Z 24mm front bar is Whiteline's recommended front bar companion for the VB WRX. Pairing both bars gives two-dimensional roll stiffness tuning -- adjust front and rear independently to achieve the exact handling balance you want. BSK025 kit includes both bars together.

VB Chassis Specific Fitment
The BSR57Z is engineered for the 2022-2025 VB WRX specifically. The VB uses different rear suspension geometry than the VA, and the bar's end configuration and mount points are matched to the VB's chassis dimensions.

Why Choose Whiteline

The RallySport Take

The rear sway bar upgrade for the VB WRX. Three adjustment positions, hollow chromoly steel, confirmed VB fitment. This is the bar that goes with the BSF51Z front bar. Installation is a straightforward bar swap -- remove the OEM bar, install the Whiteline unit with the provided polyurethane mount bushings, connect the endlinks. Start in the middle adjustment position and move from there. Adjustable endlinks are a worthwhile companion purchase if the car has been lowered, ensuring the bar operates at zero preload at the new ride height.
