Racing Suspension - Rear Steer Technology Photo Gallery
A Z-link suspension system uses a link extending from under the rear end forward to the chassis and one from the top of the rear end rearward to a mount on the chassis. The axle mounting points are on a birdcage that rotates on the axle housing. Most designs use mounting holes that would enable the team to make adjustments for the amount of rear steer in those cars. Note that the spring is mounted directly on the front link.
