The camber plates wont fix the roll center, an extended ball joint is needed.



Iv'e had belly pans on 3 cars and a boat tail on one.

Ive gotten 63 mpg in my Saturn sc1.

The Saab 96 must have a high roll center then.

Front wheel suspension is accomplished by the stub axle carried in a single angular contact ball bearing. The rubber bearings are of the type in which angular movements take place without any sliding motion whatever. All the relative movement is absorbed elastically in the rubber, with the roll center somewhat above ground level. The coil spring is on top of the upper suspension arm. A stabilizer (anti-roll bar) connects the two lower suspen- sion arms, with the outer ends of these arms connected to the steering knuckle housing by means of ball and socket joints.

The U-section rigid axle of the rear suspension system is joined to the body by a resilient bearing in the car's plane of symmetry and by two longitudinal links at the sides. The central bearing is designed to take up lateral forces and, together with the springx, the braking torque. The side links keep the rear axle at right angles to the longitudinal axis of the car and carry over the braking forces transmitted from the rear wheels.

Shock absorber movement is approximately half that of the wheels when the spring system functions without roll. When roll does occur, however, movement of the shock absorbers-which are attached to the rear axle-is considerably greater, approximately 80% of wheel movement.

The rear axle design eliminates rear-end lift under braking because brake torque produces a spring compression which compensates for this. It also eliminates sway in S-bends, as the shock absorbers react sufflciently to damp roll and thus stabilize the car.

With two people in the car the weight distribution is approximately 58% on the front wheels and 42% on the rear wheels. This weight distribution ensures good drivingwheel adhesion, keeping the load on the front wheels greater than that on the rear wheels, as long as the up gradient does not exceed 25O.
