Grow up. 2%, yes, a whopping 2% of ALL cars out there with my bar has had ANY problems at all. And so far nothing going to prove it's the bar's fault. The bolt rub happened on two carsn which is an easy fix and clearly is a Subaru tolerance issue. And two cars have had control arm troubles. And one of those cars was an '06. I'm not sure sure it's not a casting problem. That does happen you know.

You all are completely free to do as you wish, just wanted to point out that, as usual, things get blown completely out of proportion on the internet.
alltracin 06-06-2006 08:49 PM

Yes, "one" 06, but how many non-STi cars are running your bar? It might only happen in competition, but it appears the bar is just too stiff for a base '06. Two control arms on one '06 in half a season?
RedTRex 06-06-2006 08:50 PM

Actually, it is 5 broken aluminum control arms to date,

but that does not necessarily mean it is your products fault, it could very well be that 32mm is just too big, or all the broken arms are from the same bad batch.

I guess more research needs to be done.....:cool:
wrxkix 06-06-2006 10:16 PM

I will go out on a limb here since I am the one 06 WRX in which both my drivers and passenger side control arm broke. I did email you Sam and told you of the issue and my concern immediately with the first break and to give you a heads up before the news hit the boards. You and I both agreed at that time it [U]could[/U] be a casting problem. You also said I was the first you heard of anyone having this problem. Since you had no history of any problems, when I broke the second control arm, I posted here looking for feedback and to see if anyone had a similar problem and/or solution.

After the second break, I knew it was not a casting issue. I have in another thread, given my opinion on the cause of the failure. Being that I have first hand experience and have discussed this among fellow autoxers (Some who are engineers), I am comfortable with my assessment. The bar with stock springs (06 in particular) and R-comps on a tight autox course dramatically increases the potential for failure on aluminum arms.

I would not underestimate the potential for this to happen with others that autox with R-comps and have aluminum control arms. Stiffer springs will certainly help ease some of the load on the control arm. All the breaks I have heard of, seem to be exactly the same, so I see a trend forming, however small, still a trend. Random break points would be a different story. I would not hang my hat on a casting problem with the control arm.

I have not asked for any financial reimbursement, nor would I. I understand the risks of being on the cutting edge of development and accept them. However, I feel I may have a solution to the endlink/control arm problem. Given time, and after I have tested it, if I feel it is safe and durable, I would gladly share it with others.

First off, to fix a problem, we have to acknowledge the problem exists.

5 broken aluminum control arms from 4 cars is not blown out of proportion. Assuming you sold 100 fsb (which I don't think you did), you've got a 4% failure rate. All you have to do is fix the endlinks and you'll be fine with the issue. As an engineer, I have to say that is the worst type of attitude to take.

A 32mm strano bar is not too much for the aluminum control arms, as shown by the Whiteline 27mm adjustable FSBs that have been set to 29mm stiffness (since the 32mm bar is rated to be 29.2mm equivalent in stiffness). The issue are the endlink designs.

No good deed goes unpunished......

I've heard of 2. Seems to me, much like the horrible bolt rubbing, that some (not saying all) folk are taking to complaining instead of calling me. If there is an issue that's widespread, I'll work on it. But to date, I've heard of 2 arms, that's all. If there are more I'd like to know. But I'm not going to take internet heresay as proof. And I need details about what's going on under the cars (the other parts) in order to figure out what's happening.

And FWIW, for those who think the 27 whiteline is as stiff as mine on it's stiffer setting, and you think that my bar is breaking the arms because it's too stiff....... well, those two things don't balance out.

And it's amazing how people don't blame breaking rear diffs on their mongo rear bars and/or no droop travel struts that cause the inside wheel to hang in the air, spinning, then slam down breaking stuff. Just odd how people react to thinks. Front control arm breaking = my fault. Rear diff breakage = crap happens.

I'm not saying that anything is or isn't perfect. I'm saying without data getting to me, all the complaining in the world won't help. And it'd be the courteous thing to do to let me know. I appreciate the word from the two folks who I have heard from, and I appreciate the understanding this is a big bar that is designed to limit roll, and that does put a lot of load into the arms. Anyone else that has a problem, let me know. But I suspect like the "rubbing" incident, I don't think I'll hear much.... I didn't then, but there was lots of whining. If I do, I'll take steps.

+1 Steve. Thanks for your post! :)
wrxkix 06-07-2006 02:16 PM

I have no problem with the bar itself and have communicated my problem directly to Sam. However I did not call, I communicated by email. Not once have I complained, I have only communicated the facts of my particular setup and have made no assumptions on what may or may not work for others. Again the only idea Sam had at the time was a casting flaw.

I have also accepted complete and total responsibility for my decision in using the Strano FSB, nor do I regret it. I am at this point surprised that Sam is not interested in researching the issue with my car further to enhance future products. Therefore, I having chosen to try to come up with a solution by talking to others here and elsewhere to redesign the endlink attachment point. I would gladly take advice from Sam if given.

I still believe it is not a casting issue. The left and right side both failed on my car, so that in itself is two different castings. Another piece of information that may be useful is, how many people are out there running the bar on an 06 WRX with r-comps at autoxs? That may be an interesting percentage to know.

My dealings with Sam have to this point been fair and professional for me personally, but don't make assumptions about my agenda in posting on the forums. I am looking for a solution to a real problem. There are several people on these forums that know me personally and were present during both failures. They have seen for themselves that this is not a random failure. It will continue on my car if not addressed.
subieworx 06-07-2006 02:21 PM

The whiteline bar is 16% less stiff than yours, pure and simple math I guess. As you say though the stiffness of the bars is not causing the problems. I think most people agree with you. It's the torsional forces being applied by the endlinks.

Easy there McRon. Steve (wrxkix) is a well respected member in my local SCCA club and one of the BEST wrx drivers in our region. If you took the time to read his posts carefully, you'll realize he's not whining about anything but only looking for a solution. ;) Steve has been very cool and level-headed despite having to foot the bill for replacing two aluminum A-arms.

Steve is a gentleman and a brilliant driver. Listen to what he says and you WILL learn something.

No sarcasm intended. Since Steve traveled down to Triad and beat Shillock's ITR on his home turf, I definitely feel that qualifies him as being one of the best WRX drivers in our region. :)

Either way, Steve is an autoX instructor in our Blue Ridge Region and knows what he's doing when he's out there racing. :cool:

Thanks for the compliments Chike, however, I am not sure they are all deserved. We have a lot of good drivers in our region. We are lucky in that respect, it makes us all faster and smarter.

I think McRon is jesting, but without the "lol", at first I wasn't sure either. See edit in my post above. ;) Correct me if I am wrong McRon, but I believe you have had the same problem on your STi with the control arm.

alltracin was referring to McRons comment.

Sorry this got off topic, but this does seem to an issue that people have a strong position on.

You should try and keep up. It is a growing problem with the aluminum control arms using your bar. But don't worry, we are trying to come up with a way to fix your bar for you. :rolleyes: You always come off as an asshat in these threads. Makes me believe that you probably are. :mad: Also, the material used in the bushings breaks down within 3-4 months and makes the bar very sloppy. You can tighten it down, but then you get metal to metal contact between the bar and the control arm bracket. Could be why they are breaking?

None of the racers complained about the bolt rubbing, it was the daily drivers that whined. I was one to the ones that stood up and said this is a racing part and may require some creative fitting, live with it. The arm breaking problem is with racers. I don't blame you that a race part exposes a weakness elsewhere and causes a problem, but your attitude in this and 2 other threads I've read is very defensive and unwilling to reason. I would never do business with your company again based soley on that. I'm glad everyone in here loves you and thinks your an alien driver but that has no bearing on the fact that there is a trend of breaking control arms with the bar. Instead of being a jerk, a simple "I'll check into it and if there is a problem, I'll try and find a fix" instead of being a jerk. I'll try to dig up your response to requests for a different link design, that what really started me regretting the purchase of your bar. Gave a glimps of your arogance and bad business sense. This was some time before the arm thing even surfaced.

Either way, I don't want to see this thread taken off topic, and I hope a solution can be found soon.

Bad manners on my part. I thought wrxkix might have thought it was funny. After I read Sam's post I felt like he was talking about me when he said people are whining and complaining so I thought I would try to place the blame on wrxkix in an attempt to feel better about myself. My plans have backfired and now I appear to be a bigger idiot than I had originally imagined. Sorry to eff up the thread. Anyways, the product has it's advantages and disadvantages. I like it cause its the biggest bar you can get and its lightweight and hollow. It was noisy at times for me but I could live with that. I don't like the endlinks and how they attach. If you like it, thats cool too. Would it withstand the abuse 98% of us would put on it? I suppose thats possible. I think the bar would be better if you could use stock type endlinks with it. I don't think too many would disagree. Could a big hollow bar be made like that? I don't know. I admit I don't know much about anything. But anyway, if you take off your endlink mounts, methinks you will see where the threads are digging into the aluminum. I know both the joy and pain. I miss running it. I don't miss breaking stuff. I will probly get a different big bar when I got the dough to spare. I will try to be more careful with my posts in the future.

Make you own endlinks. It is very easy with parts bought from mcmaster.com or online race parts wholesalers. I would make a set to try if I had the bar. I have made front and rear for my MR2 Spyder before for very little money and so far they have worked flawlessly.
