These Del-Sphere™ pivot jointed adjustable rear lower control arms for the Factory Five Racing MK3 and MK4 solid rear axle cars outperform the bind happy polyurethane bushings that come from the factory.
Eliminate wheel hop, increase traction, and drastically improve handling with an easy bolt on installation. The Del-Sphere™ pivot joints provide for "bind-free" handling and no deflection launch performance. They come powder coated gloss black for a brilliant and durable finish.
The rear control arm bushings on the Factory Five Racing MK3 and MK4 vehicles have a significant impact on your vehicle's ride, comfort, handling, acceleration, noise and vibration. When the vehicle leans (rolls) in a turn, one side of the chassis moves up relative to the rear axle and the other side moves down.
The control arms must twist to allow for the axle to articulate, this causes the control arm bushings to bind. If this bind becomes excessive, it will raise the rear wheel rate and produce sudden and uncontrolled changes in handling such as snap oversteer.
The factory uses polyurethane bushings to eliminate wheel hop, reduce axle deflection, and improve straight line traction. However, the downside of polyurethane bushings is they prevent the necessary movement of the control arms during body roll, which in turn produces significant binding in the suspension when the vehicle is cornering.
The polyurethane bushings also place high stresses on the control arm mounts on the vehicle. Polyurethane bushed control arms do not allow for rotation of the control arm during cornering because of the stiffness of the bushings.
