Hey just have a question for those that do crazy mods to your r53. I have a set of r56 aero side skirts that i am going to put on my r53, and just wondering fastener wise what works, I know there is cutting that has to happen to the skirt to fit, but I know there are a couple people that have done this in the past and just wondering if anyone knows how they can actually be held to to car, or will stock clips actually work. And also I have a set of genuine GP rear bumper inserts I am going to put in. What is the best way to drill the holes and line them up properly in the rear bumper. Thanks
