I got a 06 r53 a I am going the put the r56 aero skirts on and was wondering what mods for sure need to be done to them. I know in 2010 there was a couple people that did it. I have the skirts and just from rough fitting know there's a spot by the rear of the door sill that needs to be trimmed and part of the arch needs to be painted the body color because it is wider, but what clips exactly do I need to find a different waay to fasten them and such? Thanks
