Did a quick search on forums for M Brace, it takes the M out, only looks for Brace and I can't find anything helpful.

Anyone have suggestions on an M Brace? Mine is pretty ugly and rusty. Missing couple bolts and making noises.

 

I can sell you mine ... I did a custom to clear my 4" exhaust...

 

Got pics?

 

It's actually called a W-brace....

There are also a lot of aftermarket replacements that seem more robust but not really sure they're any more effective than OEM.

 

Depending on how rusty it is, and if that rust hasn't compromised any of the structural integrity, I'd say remove it and refinish it yourself. Then go to your favorite hardware store and pick up some 'grade 8' bolts to replace the ones that are missing. Total cost: $20 bucks(if that).

 

I have an ultra racing w brace on mine because mine was also rather rusy... I also have an oem one in better shape...

The problem with the aftermarket one is you cant mount your plastic pieces back under the car... Other then that it fits o.k. (not as good as stock) and works fine.

If your bolts broke off in the kidney looking brace that connects to the subframe these will make for a miserable time... Dont ask me how I know.
