Introduction
In most cases, the traditional ladder-style or space-frame chassis is the foundation of the hobby motor car. The chassis supports the body and all of the major mechanical components, and keeps those components in their correct relative positions while the vehicle is subjected to the many stresses and loads imposed by acceleration, braking, cornering – and of course, our famous New Zealand roads.
Three basic types of chassis are covered here:
- high-volume manufacturers’ chassis that are modified; and
- the ‘ladder’ or ‘cruciform’ chassis which is typically a mostly flat platform, incorporating channel or RHS (box) section side rails, linked by transverse and/or diagonal cross-members; and
- the ‘space-frame’ style which typically uses numerous predominantly straight small-diameter thin-wall tubes arranged in a triangulated manner to achieve high rigidity with minimal weight.
More complex motor vehicle foundations, such as the composite ‘tub’, whilst touched on here, is such a science that it is generally beyond the scope of this Technical Manual. Note that the requirements in this chapter do not apply to an unmodified production chassis.

Background
The NZ Car Construction Manual (referred to as the ‘CCM’, and previously entitled the NZ Hobby Car Technical Manual) is a comprehensive technical manual encompassing the many aspects of vehicle design, modification and construction. Over the years the scope of the manual has expanded to encompass many types of modified vehicles. It is developed by the Low Volume Vehicle Technical Association Inc (LVVTA) and is incorporated by reference into the LVV Standards, which are in turn incorporated by reference in the NZ Land Transport Rules.
The CCM first became available for purchase online on the 1st of November 2016. Electronic downloads of the NZ Car Construction Manual became free-of-charge on the 1st of February 2021.
