Hey guys..

I've been working on a FSTB for the 5th gens.. and i just want to show u guy's my Auto Cad Blue prints for it.. The concept for the FSTB. Is to get rid of weldings that most FSTB's have.. that will cut down the chances of cracks breaks and so on... but i will post more spec's on the sway bar later on when i'm done my testes.. i have one made from light weight aluminum.. and my goal now is to get the FSTB to stay under 14.832LBS, and act like 50lbs steel bar.. so i'll fill u guy's in..

A Few Questions

I am looking into getting an FSTB and I was wondering if there were problems with the welds on other sway bars, and why you wanted one with bolts? Also, how heavy are the other ones, under 15 lbs sounds pretty good.

Is this what you do when you're at "work"?

I work at home so it's easier to play

looks good!

As a structual engineer I think the welds are better than the bolts you propose. I have not heard of any problems in the current designs. Welds, if done correctly, are stronger than the metal it joins. When welds fail it is uaually from twisting in a direction that the weld was not desighen for.

For the bolt that goes into the ring, I did not see a nut on the other end. Make sure you have clearance for the fastener. Also the 2 bolts holding the main horizontal bar may not be enough to keep the bar firm (due to play).

Keep it up! If you do get a good set of drawings, I looks like your FSTB will be easer to make. The home depot FSTB!

I was thinking the same thing, that's why I was asking the questions above...

Hey theMax, you didn't by chance go to UD did you? I graduated with a Civil Engineering degree from there a little while back...

How about titanium? Lightweight but strong. Probably too expensive, huh?

cool Home Depot FSTB that should be much cheaper to do than the Courtesy/Stillen rite?

I've been working on a FSTB for the 5th gens. . .

I'm not going to get into bolted vs welded . . .

But a big part of what makes a FSTB work is its bending stiffness and the bending rigidity of the connections to the towers. So anything that looks like a hinge (structurally) is going to detract from the functional effectiveness. I'd double up on those bolts that are used to attach the center part of the bar as a minimum (going to two bolts per side won't add that much weight). Another improvement would be to attach to the tower structures with 4 bolt patterns that cover bigger areas (not all 4 in a straight line), again, this is to improve the overall bending rigidity of the assembly.
