Whiteline Anti-Lift / Caster Kit Subaru STI 2011-2014 / WRX 2015-2019
The Whiteline anti-dive caster kit for the Subaru WRX and STI dramatically improves vehicle stability. In stock form the front end of the STI has a tendency to move around which equate to less then predictable handling. The front end will lift up when accelerating and dive to the ground when braking aggressively. The anti-dive kit, or commonly referred to as the WALK kit, from Whiteline keeps the front end under control and provides the driver with more predictable handling. This version incorporates a metal bearing for the least amount of deflection as possible and adds .5 positive degree of caster. Due to the use of spherical bearings increased noise and harshness can be expected.
this is what you need if you are going with meaty tires and a wide wheel low offset combination also improves steering response in corners great product
