Crazy Modeler Subaru Rally decal question

I have the Crazy Modeler decals for the "555" sponsored Subaru car. They provided two sets of the "555" decals. Are these provided for me to double up the decals? Do you guys usually double them up? One set appears to be covering OK for me.

Thanks,

John

could it be just an extra incase of a mistake was too be made

On my set the printing on the main sheet was not perfect, so I assumed that the printed an extra set for quality reasons. It is worth checking the number plate on the car you wish to model, as some of the decasl are incorrect if I remember rightly.
