Here's a example of things to do once you've broken a front IRM spoiler. Keep in mind-this wasn't a initial tweak (at first), but was a direct result from cracking the spoiler 2 or 3 times. The IRM spoiler sat in the garbage for nearly 10-years until I decided to use a portion of the broken part.
As you can see the part beef-ups the side of the nose w/o the continued damage using to the now deleted front portion. #011 is my favorite car to drive because I don't ever have to worry about something in the road. Was it hard to do? No. Just trim the part down to the desired tweak and have the shop glass the puppy in.
