I don't think it's any different. Here is a picture of mine before I started modifying it (or just after I started to but remember to stop and take a picture). I removed where I had the silver lines. That created a better fit for the lip on the lower oil cooler that I ultimately removed. One of the bigger differences between the BD and FFR bodies is the oil cooler. Ultimately its up to the end user but I felt it worked best by removing material around the cooler to sort of create a wrap around.

This picture is a little deceiving. The hood scoop is sitting on the hood just behind it giving the impression of material being on the spoiler that actually isn't there.

No matter what it will require both trimming and adding of at least some material either fiberglass or filler.... or both
