A standard bushing only restores what the factory built. This one is designed to change the geometry, adding positive caster and changing front anti-dive behavior, in addition to resisting the deflection that soft rubber allows.
Whiteline rates the install as difficult and lists about 2.5 hours. An alignment is required after installation. Working on the same car? We also list Front and Rear Sway Bar Kit, Front Steering Rack And Pinion Mount Bushing, and Performance Lowering Spring Kit for the WRX STI.
