Upate on Lowbuckx

[LowBuckX]

I have to finish weld and paint or powdercoat. But here are my LowBuck g-braces. Anyone keeping the lowbuck total Add $55 + powder coat.


Mounted on UCA cross shaft with 1" c channel I had hanging around from a tool I built

[SatisTraction]

i am just curious what you think that will do mounted to a flimsy firewall and to one bolt with flimsy channel? It does look kinda cool.

[LowBuckX]

That channel is far from flimsy. It is used as corner supports for glass buildings.
The bars are also tied into where the fender mounts to the firewall. The strongest part of the firewall.
Argue with HerbAdams on the engineering and speak about flimsy with his bars. Look at what he used for his UCA mounts.

Not said in anger but as Matter of fact



I also used way stronger tube and he had the convenienc of a straight shot to everything

These are not crash protection if that is what you are thinking

I am of the opinion that you were not in fact intending to derogate LowBuck’s efforts or ideas with your post. Nor do I think you intended to insult LowBuck. However, your post does demonstrate a tendency towards what can only be described as arrogance. Please explain your intentions so we might find your post to be a bit less contemptible.

LowBuck,

Pretty cool! If you haven't already, look under a GM B-Body station wagon. They used a brace that went from the front cross member, to the rear lower control mount, to the frame. I'm thinking this would work nicely with your braces, along with solid body mounts. It seems to me that you will have to utilize solid body mounts to keep from cracking the firewall. I also seem to remember Mr. Adams also used these on his T/As.

Great, exactly as I'm planning to do for my car!

Solid Mounts and subframe connectors already inmstalled...
I will have to try and find a pic of what you are taking about on the other brace.

Thanks PT442 Neki67 Go for it

[SatisTraction]

no offense meant to the guy. I just do not think it will do anything to help the car. all it does is add weight and will flex the body if the frame flexes. now if he could have tied the two control arm mounts together and then triangulated to another point it could have had some performance value. this reminds me of the strut tower brace on mustangs, however this brace is not as tied together.

[69Nova]

Very cool. I defintly want to hear your thoughts about them after you drive the car.

Have you even heard of Herb Adams. I think he knows a bit more than you or I with this engineering thing. These dont do anything that a strut tower brace is supposed to do.

see we agree on that can you tell me what they do?

[protour_chevelle]

Prevent vertical movement of the front subframe I'm guessing.

[LowBuckX]

Since imagination and geometry escape you enjoy my little illustration

[SatisTraction]

so you think that whatever flexes your frame will not have the force to flex a sheet metal firewall? if you had a cage and tied it to the cage then you would accomplish your goal.

and if that red car belongs to herb adams i know all i need to know about his engineering.

try this. unbolt them from the control arm mount and then see how little force it takes to flex the firewall. i bet a 3 year old could do it.

[LowBuckX]

Im not here to argue with you and I didnt ask you for your opinion.

[TonyL]

No sense arguing a point that has been made for oh, Say about 25 years or so. It's only been a popular, proven technology and mod for that long.

Ever hear of a Fire-am? Can one brace flex a fire wall? sure. but the fact they are BOTH tied to the firewall make the whole thing a system. It works. It's a simple as that.

[71dusterdan]

lowbuck that is sweet , how did you end up bending them? nice job bro. Dan

You can never put down any man's efforts

Regardless of the "technicalities" you know those reinforcements are doing 'something' as oppsoed to nothing... right?

I will add that the 110v AC outlet and mess shown in the 'red' car has me a little terrified Does make me wonder what BOP/C engine was in there

hahahaha...the basic flaw in one side of the thinking in this thread makes a humble engineering student like myself giggle.

Here's one theory presented in this thread about how these braces apparently work. We'll call this the "gnorw" theory, in honor of the school of thought it comes from.



This diagram is designed to show how a force acting on the frame would affect the firewall, according to this school of thought's opinion. According to this diagram, the braces are obviously pointless.

Now, here is the second school of thought's idea. We'll call this one the "ytilaer" theory.



Now in this first shot, you can see how, according to this school of thought's concept, the force of the frame pushing up would, THEORETICALLY MIND YOU, be distributed throughout the firewall, through two different points.



Now, here comes the really wacked out part of this school of thought's theory. According to them, the motion of pushing UP on the bar would actually produce a force that would push BACK on the braces! CRAZY TALK YOU SAY? Not to these wackos. They actually think they can change the direction of the force with a simple metal bar.



Finally, these nut jobs point out that, since they're using their "magic force changing directional metallic tubes" and their "super fancy force spreading mounting points", you would ultimately have to CRUSH THE ENTIRE FIREWALL REARWARD INTO THE BODY OF THE CAR IN ORDER TO GET ANY VERTICAL MOVEMENT OF THE FRAME. And since that entire firewall is supported by, oh, buttloads of metal, that's pretty much impossible.

I believe we can all see how simply preposterous this is. since these magic force tubes are only supported by, oh, say, the laws of physics (which are highly suspect these days, apparently!), there is ultimately no reason to even presume the second school of thought might be right.

Herb adams, how could we have ever trusted you? After your decades of race experience and completely revolutionary designs that are time-tested and the basis for a massive chunk of racing technology even today, the "gnorw" thinkers have finally shown you for what you truly were: a BIG FAT STINKY FAKE.

You know what? I bet ol' smokey yunick was just as big of a liar. I shall never trust another racing legend, ever again.

Remind me to throw my chassis braces out in the morning. In fact, I'll just go ask my 3 year old to yank them out for me.

edit: by the by, that red car is not herb's. Here are a few of his...

laguna seca, circa 1983. He probably snuck the car onto the course


oh, and here it is again at sears point...so you can see the other side. Agan, I'm sure his car didn't actually race there, or anything


here's his avante, from mid-ohio, 1984. Obviously a poseur.


here's one of his earlier birds...at watkins glen. In this one, you can really see how little thought must have gone into making the car fast. Gosh herb, you're such a slacker.


oh, and here's his book...filled with mindless drivel, no doubt.
