Mud Flap Extensions

AFAIK there is no maximum legal limit for mud flaps. To the contrary, the law states (afaik) that the bottom edge of mudflaps must be no more than 300mm from the ground.

However, if you make them too long so that they drag along the ground, they will throw up stones on gravel roads and be more trouble than they're worth.

My opinion is that they should be about 150mm to 200mm off the ground

Just a short note to add to that.
If by chance you are setting up the full width ones, consider mounting them on a hinge, to the chassis. This will allow them to move, back and forward, as the situation allows.,and will actually help, just a little, in economy. And with the price of fuel every bit helps.

same as mine.
just used some heavy duty rubber from clarkerubber, 4 bolts (with wing-nuts) & 2 pieces of aluminium.
whatever you use, try and put a chain on to stop you ripping them off when reversing into rough ground.
mine are easily removable also, with the wingnuts.
