Default My, er, prototype aluminum STB (pics)

So I was browsing the local homegrown speed and performance shop (that would be Lowes) and I stumbled across the metal section. Originally I was looking for beams to make my engine hanger for the trans swap, but something else caught my eye.

It'* still in the rough stages, as I do not know if I want to keep it natural, or polish and clear it, or give it a brushed finish then clear. But it does shave a bit of weight off compared to the factory. And no negative effects on handling.

So, what do you guys think of it?

Interesting I kinda like the look of that.. Contrasts nicely with the rest of that drop dead sexy engine compartment.

That looks really sharp. I'd just clear it like that. I really like the look. It'* custom without being tacky or ricey looking like most aftermarket STBs.

I want to say 1/8th inch, but don't quote me on that.

Thanks for the comments guys. I kinda like the look as-is myself, but I know it won't stay like that for too long if it isn't protected.

I really like the idea. I want to see some more ideas on it, espically from some of the elders


Side Note-- As many know i recently removed my engine and upon doing that i took the brace off and thought to myself that it was suprisingly heavy. This might be a weigh to shave maybe like a solid 5 pounds off very easily.

Not a good idea. You want what weight you have on the front for traction. And to make it worse, Aluminum has less tensile strength than steel.

You have decreased the ability of the bar to resist cornering forces and improve handling.

If the bar were SOLID aluminum, it MIGHT be better, but I'd have to run the numbers to be sure.

I suggest you go back to the steel bar.

Keep in mind all that weight over the front wheels is hurting handling, though. That'* why front wheel drive cars understeer, or push. With a NA 3800 I doubt traction is a huge issue.

I agree on the strength thing, though.

But I stand by my comments that it looks friggin' good!

IMO worrying about 1-2lbs MAX and traction on an L27 is a bit of a stretch. Unless it'* thicker, it might not be the best idea.

My issue though with anything added to the OE mounts, is that it wont be the exact dimensions most likely, and will give more points for flex, or worse while under load, and have more slop.
