Whiteline 08+ Subaru WRX Hatch / 08-09 Subaru STi Rear Brace-swaybar mount support - KBR15

Whiteline's rear sway bar mount support brace increases the stiffness of the rear sway bar mount and reduce the likelihood of bending or cracking of the OE mount due to the increased loads placed upon it. Recommended use with aftermarket sway bars for optimum sway bar performance.
