Its not the dirt which is the problem it is the stones, If you remove the flaps your front doors and cills will take a hammering from road debris, you can't wash stone chips off
Your choice Frayz.
i would keep them on the car seen some with them off and they just dont look right they suit the
car and as said as well as the dirt on the car its the stone chips that you will get up the side
of the car and as urs is black will show up more.
when I changed mine I thought it would be a good quick and easy job which it would have been if the nuts hadnt seized to the bolt on the front flaps and require cutting the bolt off :x
Frayz, can you not get prodrive Mini flaps like you can for the Classic?? I have copies of these, tehy look subtle but stop all the stones from chipping teh bottom of the doors etc.
