OEM /6 mount, Mad Dog Options

[930cabman]

Making the conversion to a 6 cyl, we have several choices to make with mounts, exhaust, fuel, oil tank, engine tin, ....

I recently purchased the OEM mount from Mad Dog, you couldn't ask for a better fit. It nestled into the recess and allowed basically no room for error. I socked it in with a couple self tapping screws and went ahead with the plug and fillet welds.
I removed the paint from the mounting surfaces with paint stripper and cleaned it up with a sanding disc prior to welding

From what I understand the factory placed additional reinforcement in this area. Running the welds for this mount I sensed it the way my MIG was acting. I bet you could pick the entire car up from this mount. Very well done Mad Dog

Here is what Im thinking for the bottm plate?

Looks pretty good.

Assumed constraints on my part based on what I see:
laser / plasma cut
Welded at seams

Need to be thick enough gauge to avoid "blowout" when the snubbers engage.

From previous picture posted I think this one is showing minor signs of heavy snubbing somwhere in it's past. Not a big deal but would be nice to proactively address it. Still totally functional as-is.



I was figuring I'd machine them as one-off but I totally get sheetmetal weldment is the way to go to keep price resonable and to match OEM look. Woundn't have any hesitation about your proposal as long as it is as thick as OEM or a tad more.

Have you considered Titanium? . . . . (IMG:style_emoticons/default/aktion035.gif) Just kidding.

Hawk, I think the thickness of the bottom plate is about 2.5 mm(.098"), Im going with 12 ga steel which is about .105" thick?

Overall I'd say that is great and pretty comparable.

The 0.007" inch won't net much in terms of increase in stiffness or durability of the snubber. The shape has more to do with stiffness than the slight add of thickness.

Might 11 gauge (0.125") work and/or might be cheaper and easier to obtain?

The downside is don't have parts in front of me to know if that thickness add of another 0.020" causes other problems as part of the overall sytem. I don't think so. I'd rather have a stiffer snubber than one that deflects.
