The front suspension comprises of unequal upper wishbones with top king-pin spherical joint, a lower arm with spherical joint and tie-bar pivoted inboard with a rubber bushed ball joint.
The suspension spring, in unit with the telescopic front shock absorber bears down on the lower wishbone assembly. Adjustment of camber and castor angles is by shims on the upper wishbones.
A front anti-roll bar completes the suspension design. Steering is by rack and pinion. The original suspension was designed for use with cross ply tyres, and as such, the turn-in and cornering is good, so long as the damping remains effective with some understeer designed in.
Changing to radial tyres with a significantly reduced slip angle has the effect of inducing an element of oversteer, and to counteract that, a stiffer front anti-roll bar is desirable. Turn-in is affected by camber angle, particularly when wider section radial tyres are being used.
The DB4 and 5 rear suspension is by twin equal length trailing arms for longitudinal location and Watts linkage for lateral location. With the DB6, the upper trailing arm is slightly shorter and this induces some natural roll stiffness.
The coil springs bear down directly onto the rigid rear axle. Damping is achieved using lever arm shock absorbers, with some ride stiffness control available using Selectaride type of shock absorbers on the DB5 and DB6.
