From the creators of the original anti lift and caster kit comes the latest addition to the program with the release of the WALK for 2008-2014 WRX.

The WHITELINE anti lift and caster kits are infamous among WRX and STi owners the world over. With a WALK fitted to your Subaru:

• More compliant suspension will be induced during braking and accelerating.
• This will benefit traction, as the wheel will be able to track the tarmac
  more precisely.
• In terms of balance, the front end will have a proportionally lower roll
  resistance during traction or braking,
• Aids in reducing the power understeer effect that is present in these
  vehicles and resulting in a greater handling Subie.
• Caster gains resulting in a sharper, more precise steering feel

The STREET option offers built in ANTI LIFT and caster properties without compromising ride quality characteristics. KCA334 caters for 1/2 degree more positive static caster (and a lot more dynamic) which is on car adjustable. Yes, thats right, its on car adjustable. The scalloped internals of the bushing combined with the polyurethane collet style spacers (also double as dust boot protectors) permits low articulation resistance, acting much like a spherical bearing without the compromise of NVH. This design all contributes to a positive vertical location of the pivot point, which is the key to ANTI LIFT and a positive handling result.
