Jettison 1's front suspension is an unequal length, double wishbone design with inboard spring and damper units operated by a pushrod. The rear suspension uses a similar design with equal length wishbones.

The cars upright and hubs have been manufactured from steel. The uprights have a five degree king-pin inclination which reduces the offset to 36.25mm. This gives good feel to the driver while minimising steering kickback. The front hubs and axles are machined from one piece of steel to simplify the machining process.

The suspension has been designed with a large degree of adjustability to enable effective tuning of the system. Ride height, spring rate and preload, damping, camber, caster and toe-in are all easily adjustable.
