Choosing the Right Part

Subaru suspension parts often differ between generations, and sometimes between WRX and STI or sedan and hatch. Check the chassis code in each listing (GC, GD, GE/GH/GR/GV, VA, VB) against your car before ordering.

Hardrace offers many parts in two materials. Hardened Rubber reduces deflection over factory rubber while staying quiet enough for the street; Pillow Ball (spherical) removes deflection entirely for the most direct feel, with more noise and harshness, and suits track-focused cars.

Installation & What You'll Need

Installation by a professional is recommended. Many bushings are press-fit and need the arm removed and a hydraulic press. Any adjustable arm, link or roll centre adjuster changes alignment, so book a wheel alignment straight after installation.

FAQ

Will a part fit both WRX and STI?
Many parts are shared, but some differ between WRX and STI or between generations. Each listing names the chassis codes it suits.

Should I choose Hardened Rubber or Pillow Ball?
Hardened Rubber suits street-driven cars, giving more precision without much added noise. Pillow Ball suits track-focused cars where feedback matters more than comfort.

Do I need a wheel alignment after installing these?
Yes. Adjustable arms, links and roll centre adjusters change alignment, so book one straight after installation.
