Lightbulb DIY frame rail reinforcement...

So I was thinking about FM's frame rail reinforcement...when a friend of mine showed me his. Aluminum rails out of computer server racks! Perfect width. Just cut to length, slip over rails, drill holes, and bolt up! (unless your rails are beat to s#*t like mine) So after some "massaging" in they went..cost me $18.00 in hardware...as opposed to $199.00. Here's a few pics:

Did you just bolt through the sides or did you bolt up through the floor as well?

thats cool, but the point of the FM rails is that they mount to the floor pans increase the stiffness along them.

Good idea though. if you mount some traverse reinforcement across those racks I am sure you will get a noticeable difference

Where did you get the rails? Do you have a part number or something?

I like this idea alot. Your gonna connect to two rails next right? What exactly from a shelf is that?

This makes me want to get two street sign posts and a sign to connect them both. I remember seeing a miata with a street sign under the car somewhere.

Very innovative, sort of I guess, great idea, I like $18 much better than $200.
I just might copy you here.

I can see some grinder work and perhaps some hammering. Was it that the rail was slightly wider than the track in the bracing, or was your rail uneven down it's length and you just smoothed it out.

How did you hurt your frame rails that bad in the first place?
What is the width of the rack you're using?

Do you think that these braces would "slip" over an unmolested frame rail?
What would be ideal is if the brace .001" wider than the rail and you would simply tap it up into place with a rubber mallet. Rigging up a crossbrace would be a really simple proposition.

Is there any dramatic difference in the undercarriage between the years. I know FM's brace is "universal", but is there anything to consider along those lines?
