CSCRA 1/32 Hard-body Car Classes - Scratch-Built
1/32 Car Classes and Standards
In classic 1/32 slot car racing the emphasis is on scale and historical accuracy to the real 1:1 racing cars. The CSCRA car standards set reasonable and realistic guidelines to achieve this, while enabling and encouraging continued development and innovation in chassis design and the use of the latest equipment.
The car standards documents for the individual classes include general car standards as well as details for the specific classes.
All the documents are in pdf format, for reading on-screen or downloading. In the documents, blue text signifies definitions, and red text clarifies potential areas of dispute.
Retro Plastic-Chassis Class Rules
Some of the most popular club racing in the UK is in classes for older models from Scalextric and other makes. Some of these classes are run in open events, and we make the car standards for these events available in case clubs want to take advantage of these ready-made rules.
A number of clubs in and around Birmingham have been racing classic Grand Prix cars powered by the Scalextric “Johnson” motor in the Heart of England Classic Grand Prix Championship. The 2012 rules are here:
Vintage 1/32 Scratch-Built Hard-Body Class Rules

Car Dimensions Information
A very handy summary table of key CSCRA scrutineering dimensions (such as ground clearance, tyre width etc) for each class is .
To help scale builders get hold of the correct dimensions for their models, Mick Kerr has kindly made available his Excel spreadsheet which includes the critical dimensions for GP cars up to about 1969.
The Scrutineer's Dimensions handbooks from Model Cars magazine have been a valued source of key information for scratchbuilders since there original publication in the 1960's, but are sadly now hard to find. So we have now made the latest, December 1968 edtion available as a pdf file.
