Recently installed the J's Racing Roll Centre Adjuster (RCJ) on my RB1. From what I read (taken from the nungen website), lowering vehicles alters the suspension geometry angles which in some cases can actually increase body roll and reduce cornering performance. The roll center adjustment kit enables the vehicle to be lowered without detriment to the suspension system. It
1) Decreases body roll
2) Improves tire contact patch with the road
3) Increases steering wheel responsiveness
4) Enables increased cornering force.
Graphic explaination from the J's Racing site which I don't understand, but the pictures looks nice

Personally, my car had abit of bump steer and on uneven roads the steering wheel would sometimes track to one side. After installing the RCJ, the side tracking on uneven roads is gone, bump steer is gone and it seems to handle corners better especially if the corner is over an uneven surface.
So now to some pictures
The box that it came in

The people at pedders had to remove the brake rotor dust covers as it was in the way
