With the ALK fitted to the Subaru WRX/ STi, a softer suspension will be present during braking and accelerating. This will help traction, as the wheel will be able to track the ground more precisely. Also in terms of balance the front end will have a proportionally lower roll resistance during traction or braking, aiding in reducing the power understeer effect that is present in these cars.

The STREET option offers built in ANTI LIFT and caster properties without compromising ride quality characteristics. KCA334 caters for 0.5º of increased positive caster (and a lot more dynamic) which is on car adjustable. Yes, that’s 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 articulation resistance , acting much like a spherical bearing without the compromise of NVH. This design all contributes to a positive vertical resistance of the pivot point, which is the key to ANTI LIFT and a positive handling result.
