So as some of you noticed I am in process of removing the old four mounts. As I got them most of the way off I am seeing our little friends (IMG:style_emoticons/default/sad.gif) It doesn't look like it is really rusty but it has thined out the metal a bit. What is the best way to take care of this? This is an autocross car and sees a bit of twist of the suspension.

Thanks (IMG:style_emoticons/default/beerchug.gif)

Sorry about the poor quality pics. I just ran out and snapped them quickly.

if it were me, and it will be soon, I would treat the metal for rust, weld a plate over the area and run you a brace over to the suspension pivot. IMHO (IMG:style_emoticons/default/smile.gif)

Do you have a chassis stiffening kit installed on the other side of the rail?

That is really all I am thinking of doing but I would like to hear from other guys what they have done. I know there will be some bracing done here as well. (IMG:style_emoticons/default/drunk.gif) We have some very talented guys on here and I am sure there is some good learning to come from this (IMG:style_emoticons/default/beerchug.gif)

That's what mine looked like. I think the metal was still plenty thick and I just cleaned it up and primed it. Looks a little pitted, but i think it will carry the load fine. Then again, I don't plan on trying to twist the dickens out of it, like do will.

Damn makes me wish I didn't have a four so I could do that, also makes me wonder whats under my mounts???


The only true way to get rid of rust like that is with one of those little sandblaster things LINK. A total bitch but worth it I think. I went through 500 pounds in my trunk and hellhole though maybe I'm just a masochist

Just patch it up and take the opportunity to add some triangulation to your suspension console ...

Jon,

I had similar rust issues when I removed my 4 cyl mount on that side. Mine was a bit worse. I think yours is probably still pretty solid. If i was you I would...

1. Media blast it. Especially to remove any rust from the pitted areas that will be hard to get out via grinding or wire wheel.

2. Treat it with Ospho and POR-15

3. Reskin the outside with new metal. I replicated the divit on the bottom right via some extra work on my new skin.

You can see some photos of mine here...

Thanks Richard. I think what you did will be a little overkill for the section on my car as the rust appears to be localized in the upper area of where the mount was. I am going to clean it, kill the rust, and weld a new nice piece of metal with a brace to the suspension. Almost exactly what the yellow car above has. (IMG:style_emoticons/default/welder.gif)

Since you're gonna be under there, stinger in hand......DWD alert! (IMG:style_emoticons/default/biggrin.gif)

The factory welding on the underside of the suspension console cries out for help.
Seal welding the pointy end of the pinch seam around the ear, then foreward to the firewall & aft to the trans mount will help prevent the cracking on the ear and at the arch over the axle. Smooth out the welding when your done. Piece of cake.
I got away with no cracks and with no other structual fixes for 6-7 years of hard AXing with this done.

BTW, don't get near that rust with Por-15......Rust Mort or Ospho with a coat or 2 of etching primer will see you thru ....till next time.(IMG:style_emoticons/default/biggrin.gif)
