Nerf bars - Do I need them?
 

After scouring the CTR conversion thread and looking for a supplier, I haven't been able to find an easy plug-n-play nerf bar for my fiberglass bumpers I'm installing this winter. My question: Knowing they probably won't do much in an accident, do I need them? Is it a "peace of mind" thing? Or should I seriously consider finding someone to fabricate something?

This is my first fiberglass project, and I went with good MA Shaw bumpers.

The help and opinions are appreciated!
