A Locost is a home-built clone of the Lotus Seven. The car features a space frame chassis usually welded together from mild steel square tubing. Front suspension is usually double wishbone with coil spring struts. The rear is traditionally live axle, but has many variants including independent rear suspension or De Dion tube. Body panels are usually fiberglass nose and wings and aluminium side panels. Each car is highly individualized according to the resources, needs and desires of each respective builder.
The original design was intended to be built from scratch. However, the design has become so popular that several fabricators have begun producing the chassis in kit car form. Additionally, fiberglass body components, suspension pieces and other Locost-specific components can be sourced from various suppliers.
