ST Suspensions 21mm Adjustable Front Sway Bar

For 1984–1989 JDM Toyota MR2 AW11 and 1985–1989 U.S.-Market Toyota MR2 AW11

Overview

The ST Suspensions 21mm adjustable front sway bar lets AW11 owners tune front roll stiffness to suit their suspension setup. It fits the 1984–1989 JDM Toyota MR2 AW11 and 1985–1989 U.S.-market Toyota MR2 AW11, with naturally aspirated and supercharged applications.

Matching pivot bushings are included. The effect on handling balance depends on the car's springs, tires, rear setup and selected adjustment, rather than bar diameter alone.

  • Front-only configuration: No rear sway bar is included or required.
  • Steel construction: Black powder-coated finish.
