Complete Rear Alignment Correction: Camber and Toe Together

Control arm geometry determines the relationship between the wheel, the hub, and the chassis as the suspension travels up and down, the control arm geometry defines how the wheel’s camber, toe, and track width change. On a stock suspension alignment, the control arm length and geometry are fixed from the factory to a specific alignment specification. When the car is lowered whether through lowering springs, coilovers, or even manufacturing variation the control arm geometry changes relative to the intended design position, producing camber and toe that falls outside the factory specification range. Cobb’s adjustable control arms add adjustment capability to bring the alignment back within specification, or to set the alignment to a more performance-oriented position.

Spherical Rod Ends and VA WRX/STI Lowering Alignment Solution

Adjustable control arms use eccentric bolts, slotted mounting points, or adjustable length rod ends to provide a range of adjustment at the wheel. The camber-adjustable rear lower control arm allows negative camber to be dialed in at the rear negative camber keeps more of the tire contact patch on the road surface during cornering where suspension load causes the wheel to lean outward. The toe arm adjustment provides rear toe control small amounts of rear toe-in improve stability under deceleration and during the entry phase of corners. Both adjustments are made with the car at ride height and locked in place they do not require ongoing adjustment during normal driving.
