Mudflaps are a common sight on rally cars, but what are the regulations for them? In this blog post, we will take a look at the MSA regulations for rally mudflaps.
The MSA, or Motor Sports Association, is the governing body for motorsport in the United Kingdom. They set the regulations for all types of motorsport, including rally racing.
The MSA regulations for rally mudflaps are in place for safety reasons. The purpose of rally mudflaps is to protect the rear of the car from debris that is thrown up by the tyres. The mudflaps help to prevent the car from spraying water and mud onto other cars, spectators, or marshals. Additionally, mudflaps can also help to prevent the spread of diseases that can be carried by water and mud.
The specifications
The MSA regulations for rally mudflaps state that all rally cars must have mudflaps fitted behind each wheel. The mudflaps must be made of a flexible material and have a minimum thickness of 4mm. The mudflaps must extend at least 40mm on each side of the tyre tread and to within 80mm of the ground when the car is unoccupied.
If you are planning on competing in a rally, you will need to make sure that your car complies with the MSA regulations for rally mudflaps. You can purchase rally mudflaps from a variety of sources, including PolyWard, other online retailers, and motorsports shops.

Mudflaps for street use
Not all mudflaps are for rally or competition use, and plenty of enthusiasts put various types of mudflaps on their daily and weekend cars.
