Alright,

I don't have an Aero Kit yet, but I do have my driving lights. When I get the Aero Kit, will I have to pay AGAIN for the installation of the driving lights onto the aero grill? or will they just do the job all over again? This had me thinking....

 

I don't have the aero kit but have the aero kit grills on my MCS with rally lights. The lights can be removed from the brackets that hold the lights. The aero grill has to be modified slightly to accomodate the lights. You should not have to pay again for the installation.
