I Installed my frame rails a few weeks ago and I took some pictures.

Tools needed:
Drill
5/16" bit
Sockets/Wrenches
Ratchet
Ratchet Extension
Safety Glasses

Start by raising your car, please exercise caution


This bolt needs to come off so we can remove cross brace, we will not be putting it back on


A view of the driver's side


… and it's out


Now we remove the  brake and fuel lines


This brace looks bent, I don't know if it's supposed to be that way. Needs to be removed also


Use a 14mm


And a 17mm


I don't think you have to, but I removed this bolt so I could move the lines when installing the rails


I didn't notice there is this bracket all the way in the back, heads up if you're installing


To insert the rails, you have to scoop the lines this way:


Then push the rails in to place


EXTREMELY IMPORTANT !
The alignment is critical so be careful, it's pretty easy once you are there, but only
drill when you are 100% confident:


Drilling time!


No turning back now...


I drilled the Right side bolt first, then the left


I tightened the bolts without rubberized undercoating first


Here's where you use the extension (unless you have a buddy to help)


Both of these are 5/16"


Almost at the end, make sure the bolts are on nice and tight!


This is what the last hole looks like


A shot from the top


And we're done with the passenger side!


The other side should be much faster and easier, hit the holes with rubberized under
coating and you're done!


I haven't installed the brackets for the lines yet but I will update as soon as I get a chance.

Also, I haven't put the cross brace back either FYI.

MINX helped me with my install and pointed out that I should drill the brake line brace hole out to the correct size before I fitted it to the car since it's much easier to do then. Not sure if this is still an issue with the FM rails so check first.

I'd like to add remember to separate, the supplied bolts by length before hand, the shorter ones go on the side with the lines.

Other advice on basic technique:

1.  Drill the first hole and insert a bolt with a nut finger tight then move to the next hole.  Repeat this until all the holes are drilled and you won't have to worry about reaming out a hole that doesn't line up.

2.  Once all the holes are done, take the bolts out and do some rustproofing on the bare metal.  Rattle can first and undercoating once dry is best.

3.  Once the rustproofing is dry, reposition the rail and reinstall the bolts with a generous bead of silicone.  It will seal and serve as threadlocker.  Torque the nuts to spec realizing the OEM undercoating will compress a bit.

So I gotta ask...
How much of a difference are we talking about in handling?
The MSM is as stiff as the factory made the car...is it that much of a difference?

When i did mine I barely noticed a difference. The best part is now I have a great jack point instead of the pinch welds.

But recently I've been running without the oem butterfly bracing and don't notice a difference. I wonder if that means the oem butterfly brace does nothing, or the frame rails compensate enough to not notice a difference.

When I jack up my car on one corner, the other wheel on that same side gets airborne MUCH earlier than it used to so it must be doing something.

I finished this just 2 weeks ago but I have been too lazy to post pictures and stuff lol... will do it tomorrow, hopefully  laugh

Since I already had the carpet out, I felt like installing some sound deadening material to the inside, then I felt like installing new speakers on the parcel shelf. I found I am not the only one that has done this when installing frame rails.

Not sure if I should post the sound deadening/speakers install here :/

Here’s a little more information on what I used for sound deadening and insulation:

http://www.mazda-speed.com/forum2/index.php/topic,24159.105.html

As far as the speakers go, I couldn't be happier. I tried to post a "how to" shortly after my install but I was a little burned out from all the work, never got motivated to post it lol

If I can find the pictures I will try to post that "how to" again Smiley

I think OP had them painted, or powder coated that color.  No difference since the SS doesn't corrode anyway.

That's correct, had a bottle of Torque N' Teal lying around and decided to waste it on my Frame Rails. Powdercoating would be really cool now that I think about it  afro
