Changing one part of a suspension often shifts the balance of the whole car. A kit that supplies both ends together keeps the front and rear working as a pair instead of fixing one end and leaving the other behind.
Installation is rated difficult, with about 6 hours of work listed. An alignment is required after installation. Other Whiteline parts we list for the WRX STI: 14mm Adjustable Front Camber Bolts, Adjustable Front Sway Bar Link, and Rear Subframe Mount Bushing.
