How to build a car for rally

Rallying is one of motor racing’s most exciting variants and thankfully it’s also pretty accessible for most people. A rally car is essentially a small hatchback with a roll cage and other safety features. Of course there’s more to it if you’re considering an assault on the World Rally Championship, but if you’re thinking of entering amateur events, find out how to build a car for rally that will be quick and safe.


Choosing the right chassis is the basis of a successful rally car. The car needs to be relatively modern but anything built within the past 10 years will be strong enough and modern enough for most amateur motorsports enthusiasts. The condition of the car’s not that important, particularly in terms of its cosmetics but you need to buy something in good working order as having an MOTis essential for British rallying competitions.

Roll cage

As you’d expect, you can’t go rallying with a basic road car. To compete at the lowest level of organised motor sport you need to install a roll cage. In the UK, the MSA control motorsport regulations so you’ll need to purchase a roll cage that meets their stringent specifications. You’ll find out all about the current specs for roll cages in the MSA Year Book, which is commonly referred to as the Blue Book. Visit msauk.org for more details. Once you’re aware of what you need a firm like customcages.co.uk can provide you with a cage that meets the regulations. You can actually build your own roll cage to the MSA’s specs but you’ll need to get the cage through the Custom Cage weld test before you are given the Letter of Conformity which the rally scrutineers will ask you for.


You’ll need tyres that meet the MSA’s specs, a race suit, gloves and a helmet as a minimum before you’ll be allowed to compete in any rally in the UK.
