Toby & list, You have my full attention on this one. My opinion, excuse the cliché, is that you are trying to make a silk purse out of a sow's ear. If DMC stayed in business, there would probably be a recall on this part. I don't think that a simple bolt-on kit would be safe because it would change the stresses on an already weak part. Before anything is bolted on, the bottom should have a plate welded on to box it in and -- more importantly -- more metal needs to be added to the outermost edge of the arm. Have you seen the photos of Tom Long's broken control arm? If anyone were to do all this welding, then they might as well weld on your modifications instead of bolt them on. There have been lengthy 'off list' discussions about designing a better front lower control arm and making a new geometry heavy duty sway bar fit. I wish that the moderators would allow more brain storming about ideas such as this on the DML, but they are more interested in seeing posts about what has been done rather than allowing the list to be cluttered with speculation. So I'll give a summary of what we came up with so far: To start with some name dropping, Steve Wynne of DMC Houston announced at the SEDOC event last September that he had plans on the drawing board for producing a new front suspension that would replace (or eliminate?) the front sway bar. This included what he described as an "A" arm that would replace the weak OEM lower control arm. Keep in mind that the front sway bar works primarily as a wheel locator bar which makes reengineering very difficult. Without the bar, the control arm would fold back. Even if the arm were made stronger or in an "A" shape or triangulated (as you all it), if it didn't bend then the frame surely will. Of course your idea would reuse the old sway bar, so this wouldn't be a problem. (I'm just explaining some background for everyone else.) From what Steve described, I think he is proposing a weld-on fixture that would connect between the front suspension of both wheels. Something like this could be made strong enough to eliminate the need for a wheel locator bar. Considering that his Stage 1, 2, etc engine upgrades are not sold as kits, I assume that such will be the case with his suspension upgrade if he ever gets around to making it. Such a setup could add substantial strength and eliminate the need for a wheel locator bar. Like you, I have considered a new control arm design that would attach to the outer points on the frame instead of at one point in the center like the OEM does. (Many people have independently come up with this idea.) This could still use a connection in the center making it look like a 3 ring hinge or it could eliminate the center connection which would then need to be replaced with a spacer. For what it's worth, I don't think this idea is practical unless a new fixture is made to bolt or weld around the frame that would connect between both control arms. The advantages of this is that it could add substantial strength and eliminate the need for a wheel locator bar (which would then make room for a more simple sway bar). And even without a bar, it may improve handling because the OEM bar does little to stop sway anyway as its primary function is as a wheel locator. Taking all this into consideration, my plan is to make a new heavy duty sway bar that could bolt up to the OEM control arms. However, I don't mean for this to be done without either replacing the arms with improved aftermarket ones or having the original arms substantially reinforced. My main concern at this point is that the OEM-size sway bar studs might be too thin to be strong enough to support the added stresses of having a real functional bar that actually does the job of a sway bar in addition to being primarily a wheel locator. What compounds this problem is that using a thicker bar will proportionally make the OEM-size stud a high stress point. The engineer suggested turning down the ends of the bar on a lathe so that they would be gradually tapered. This would distribute some of the load away from the stud. This sounds like a great idea to me and is the one we are planning for now. The alternative is to use a thicker stud which would then require a larger bushing and a custom lower control arm. And if this is the way we end up doing it, then I would expect anyone buying the heavy duty control arm would as a matter of course also not want to risk using their weak OEM control arms even if they could be made to fit. Then we would sell a complete kit that includes a new sway bar, control arms & bushings. Considering the additional fore/aft stability that this stiffer bar would provide (particularly if we used nylon bushings instead of rubber), it may give all the handling improvements we are looking for and make the "A" arm/triangulation idea a moot point. Food for thought. I have learned a lot from the extensive conversations I have had with the owner of Addco (who made the rear sway bar accessory for the DeLorean) and with the engineer who designed it (he is now working for himself in Florida and is the one who is going to make the new front sway bars.) I originally thought that we would have to temper the new sway bars after they were made, but this is not the case. Instead they start with certified pre-tempered bars and cut & bend them to shape. That really simplifies the process. But what makes this so damned difficult for the DeLorean is that this is more than just a sway bar; it is also a critical wheel locator, so dimensions and integrity are critical. Normal sway bars have fittings welded on the ends which are not tempered afterwards. But since we also need it to work as a wheel locator, any welding to the ends may weaken it too much. Then we are looking at having to re-temper them which is a can of worms better left unopened. So far it looks like the process is going to be: 1) starting with a straight pre-tempered bar and turning it on a lathe to taper the ends and cut threaded studs. 2) the bar is bent to shape such that there is more threaded stud on the ends than necessary. This is to give some breathing room because if the studs are made too far apart or the bends not done exact enough, then it can't be turned on a lathe again once it is bent. 3) spacers (washers) are placed on the ends to fill in the breathing room. 4) bushings must be welded to the front of the bar to match the OEM design. This stabilizes the bar laterally. Welds at these points won't adversely affect the tempering of the bar. The next step in this project is for me to sit down at my drafting table and whip out some engineering drawings of the OEM bar. It would seem that I could just send a sway bar to the engineer, but additionally he needs engineering drawings because we are changing the shape (that's my job) to increase the car's turning radius by stopping the wheels from rubbing the bar. This is even more critical for those of us with wider aftermarket rims. I have asked the list for help from anyone who is sitting on a copy of the factory design drawings that show this bar. It could save me some time & effort, but so far no one has come forth. Meanwhile I have other projects that I need to finish first such as making all these convex mirrors I have promised to so many people. (sigh) But oh what fun we are having! Toby, you are welcome to comment, suggest & criticize on a wholesale level all you want. You are the materials expert here. All the help I get will be appreciated. Walt Tampa, FL
