I can't speak for your car, but for most cars owners do everything they can to eliminate 4ws, not add it to a car that doesn't have it. It makes handling unpredictable and promotes understeer on my car. My car only has a toned-down version of 4ws, which I already went through great pains to eliminate by welding the rear control arms. The Galant VR-4 has the full-blown 4ws and they almost always get rid of it. Nissan guys like to get rid of HICAS, as well.
