The cars drivetrain consists of a chain and sprocket drive to a solid rear axle which transmits torque through equal length constant velocity (CV) shafts to the wheels. A 60 tooth rear sprocket was manufactured to provide optimum acceleration. This allows us to obtain a final drive ratio of 4.00 using a 15 tooth front sprocket.

The choice of using a solid axle can have some negative effects on the handling of the vehicle, especially in tight corners due to the rear wheels needing to slip. To minimise this effect Jettison 1 has a narrow rear track and a relatively stiff rear spring rate. This assists in unloading the inside tyre in a corner and allows the tyre to slip.

The advantages of a solid rear axle are:

Can use a single rear brake assembly, which reduces weight.
Can offer superior traction in straight line acceleration.
Reduces rotational inertia, making the car more responsive to drive.
Much lower initial cost and no maintenance.

The driveline uses Ford Telstar CV joints which have internal splines. This has reduced manufacturing costs of the CV shafts and rear axle as only external splines were required to be machined on the shafts.

Brakes

The braking system consists of cross drilled rotors and four pot callipers at the front and a single inboard rotor and two pot calliper at the rear. The brake callipers and rotors are production items from a 1993 Yamaha FZR600.

Two pedal operated identical 3/4 inch master cylinders provide hydraulic pressure to the system with a mechanical bias bar to adjust brake force distribution.
