Whiteline Front and Rear 24mm Sway Bar Kit – 2004-2007 Subaru WRX Sedan

Maximum Anti-Roll for the GD WRX Sedan
The Whiteline BSK007M bundles a 24mm front sway bar and 24mm rear sway bar into a matched kit for the 2004-2007 Subaru WRX Sedan. Both bars are blade-adjustable, and the 24mm diameter provides maximum anti-roll stiffness appropriate for track-focused builds. The matched diameters ensure the front and rear roll stiffness distribution is calibrated for balanced performance at the limits.

DETAILS

• Front and rear 24mm blade-adjustable sway bars
• Matched diameters for balanced roll stiffness distribution
• Solid spring steel, silver powder coat
• Includes polyurethane mount bushings and all hardware
• Fits 2004-2007 Subaru WRX Sedan (GD)
• Maximum stiffness option for track-focused GD builds

Why Matched Diameters Matter
Running a 24mm front bar with a much smaller rear bar produces severe understeer under steady-state cornering. Running a 24mm rear bar with a smaller front can produce sharp oversteer on corner entry. Whiteline’s matched 24mm kit is calibrated to distribute roll stiffness evenly front to rear, maintaining the GD WRX’s neutral handling balance at the highest stiffness level.

Track-Focused Application
The BSK007M is the maximum-stiffness sway bar package for the GD WRX. It’s appropriate for dedicated track cars, autocross builds on sticky tyres, and any application where body roll needs to be minimized. For street driving, the 22mm BSK007 typically delivers a better balance of performance and daily usability.
