Thread: Tubular front control arms

You must work for an ISO company?? FMEA's used to be my life in my last job.

Here at OEM we do our own Failure Mode Effects Analysis. We analyze the product and all of its potential failures, then we take it to the next level and reinforce. We have taken many steps to increase performance (weight gains) and safety considerations.




To be honest things could happen ... just like a Prius, or BP you can design a product, test it and it could still have a problem that you could have never imagined.

We have been building quality, well built, strong products for a while now.

If you have questions about integrity please ask and we will do our best to explain the steps taken to reduce their effects to as close to zero as possible.

The arm uses superior materials, superior welds and superior additions such as the rod ends and the delrin bushings. The arm has been reinforces using .25" plate, plasma cut to conform to the arm dimensions thus leaving less of a gap and more contact for reinforcement and unlike conventional tubular arms we have taken into account failure points with reinforced "soild" construction.

More pictures of the New arms installed. Here you can see the true advantage of our arm. Perfect 90 degree angle. Also notice that its adjustable too. So if you have coilovers you can adjusts accordingly.

I am still interested just let me get my ducks all in a row. I will pay for a set within 3-4 weeks.

Yep, I know what you mean. Sounds good just let us know.

Yes, if you are doing 100 or tracking the car I guess. And you are correct,the new arms are 1.8lbs lighter on each side. Please dont tell me we spent 3 months of design and 2 different arm styles for you guys to bash us without even seeing any results. We took on this project to better the outcome of the car and to fix a MAJOR problem.
Please tell me there is still interest in these.


I was just asking a a question. I am not bashing anyone. Like I said before I like the design. I was asking because (a) the weight reduction, which is not in itself a bad thing, and (b) the stiffness of the new assembly because of transfer forces that will be involved. What I am saying is just don't concentrate on the failure potential of the new part. Where are the transfer forces going, and will it fatigue a struture that attaches. Was there an amount of flex built into the orginal arm, is that part of the weighted design that is in it.
Not bashing, just asking.

I just drove on these and all I can say is WOW!!

Car is much more responsive and dare I say it "Crisp" on turn in. I actually scared Mark with my 90 degree turn ins at full throttle. It's on the lift now for inspection and all is well.

Get these now while you can!!

1.8lbs is a reasonable drop in weight. I saw previously in a post where it states an arm was "10 lbs" lighter. I assumed that was a typo and was 5lbs per an arm which still is alot of drop, which is why I questioned. 1.8lbs on the other hand is fairly normal weight drop.

It is very good to hear that there were months of design. I have just seen way too many times designers/engineers overlook important factors in a design. There are PLENTY of ways to f up a design especially a suspension component that could seriously hurt people. Hopefully you guys have proper insurance to cover you guys.

I can see somethings I would do different/improve, but I don't see anything that makes me think these would fail under normal life cycle.

Don't take my comments as attacks or anything... I just come throw things out as critical review like I do of all designs I work or look at. (it doesn't appear you are here, but just wanted to say it)

Looks like these are hard welded for certain sway bars (progress), will a ST or stock bar still work with these? Also, many of use have rear bushings for added caster, is there an option to get the arms without the rear bushings (as they would just get thrown in a box and forgot about)? Or do these arms only work with those bushings?

My point too.

I would like to know about this too, especially the question about the sway bar will the factory one mount with out modifications?
