Driver-Side Fender Well Blew Out

[trevxv3]

So I was mobbing down the 15-S a couple nights ago. It was empty so I decided to kinda push my car a little bit and cruised at about 120-125 down to oceanside, from where I live in the Inland Empire. I pulled into my friends house and noticed that I had this grinding sound. After pulling up, and parking, I noticed that the fender well was basically shredded up to about half way up my wheels, and the plastic underneath my bumper is torn up too.I believe its because somehow the bolt that attaches the front bumper to the driver-side fender somehow got detached and made it loose, but im not too sure. This is kind of really a huge effing bummer. What I was wondering is what can I do to prevent this from happening again. I will attach pics when I get home so you guys can see. I have the fender lining on the way from partsgeek.com and my pops has an altima too so he is gunna help me put it in. But yea, any help will be greatly appreciated

Sounds like it was loose to begin with. It doesn't just come undone. You can buy those clips/fasteners off of eBay. That's what I did when I went to install my HIDs and noticed 3 were missing.
