'The North London Society of Model Engineers organised a series of 1/32 scale retro races throughout the 1980's and 90's based on slot cars that might have raced during the 1960's, using components from that era. The current popularity of classic-style racing has developed from these beginnings.

For scratch-builders and retro slot car enthusiasts the Vintage Slot Racing Newsletter has hosted a large collection of car plans from Model Cars Magazine dating from 1951-1972 which are an invaluable help in constructing accurate scale models. This website is now defunct, although, for the moment, a lot of the material can still be found here. Work is currently underway to make all the available Prototype Parade plans available to download from the CSCRA site - this should be online during 2018.

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.


Throughout the UK, some of the most popular racing 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 other clubs want to take advantage of these ready-made rules.
