Whiteline Brace - Control Arm Support Subaru Impreza/WRX 2007-2016 You can never have too much chassis stiffness. This Whiteline kit light weight aluminium support brace replaces bowed or warped OE plates which minimises control arm chassis flex on your vehicle resulting in improved turn in. Chassis bracing maintains alignment angles and spring rates by greatly reducing body or chassis flex. In fact, it helps every component in the suspension system do its job properly and you can feel the difference through improved turn-in, sharper steering response along with greater steering feedback. : Subaru Impreza Estate 2007-2012 Subaru Impreza Hatchback (GP) 2012-2016 (Excluding 2.0 Hybrid 4WD) Subaru Impreza Hatchback (GR/GH/G3) 2007-2012 Subaru Impreza Sedan (GJ) 2011- (Excluding 2.0 4WD 272HP) Subaru Impreza Sedan (GR) 2007- Subaru WRX Estate/Hatchback 2011- Subaru WRX Sedan (GJ) 2.5 4WD/STi 2.5 4WD 309/321HP 2011-
