Stepped up from the 22mm street bar, the 26mm BSF47Z is for track-focused VA WRX builds where aggressive front roll stiffness is the priority. Three adjustment positions provide fine-tuning within the performance range.

VA WRX at 26mm
The VA WRX responds to front bar stiffness increases with reduced body roll and sharper turn-in. At 26mm, the BSF47Z is appropriate for track days, autocross on grippy tires, and VA WRX builds where the front bar is part of a complete performance setup. Running 26mm without matched rear stiffness shifts the car toward understeer.

System Calibration
Pair the BSF47Z with the BSR47Z or BSR50Z rear bar for balanced roll stiffness. Matched front and rear produces a flat-cornering, confidence-inspiring result. Mismatched stiffness produces an imbalance that requires driver compensation.

Three Positions for Track Setup
All positions are in the performance range. Middle is the standard starting point; adjust based on rear bar spec and handling feedback.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979. Every product in their catalog is developed with a clear goal: measurable improvement in handling, stability, and tyre contact. Whiteline’s polyurethane bushings, sway bars, control arms, and alignment correction kits are engineered using finite element analysis and validated on track before they reach the market. Their components are direct-fit, bolt-on solutions designed for enthusiasts who want real performance gains without fabrication or custom work.

The RallySport Take

Track-level front bar stiffness for the VA WRX. Use in the right context with matched rear hardware. 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.
