Safety straps retain the radius arms in proximity to the vehicle body should one of the front securing bolts happen to come loose.

Putting the front and rear pivots of the wishbones so far apart meant that the radius arms could be eliminated.

It can be further simplified, if needed, by substituting an anti-roll bar (torsion bar) for the radius arm.

The radius arms were sprung inside the fuselage.

The Series 2 cars, with Bristol-built bodies, had triangulated trailing radius arms for improved toe-in control.

The forward radius arms were increased in size and rigidity, to act as a semi-wishbone.

Its simple conventional undercarriage had a single mainwheel on each main leg and radius arm.

The wheel pairs are set in radius arms and have a simple coil spring suspension.

The use of the mirror resulted in the measured angle being twice the angle included by the index and the radius arm.
