OMG WTF?
Porsche 996 adjustable arms made out of 6061 aluminum and QA1 XM series rod ends…just…like…the…ones…i…use…
unfreaking believable…sic’em boys
I’m gonna chip in one thing in Bing’s defense that no one seems to be paying any regard to. Overbuilding suspension components for a 15 yr old car is STUPID. If you ever encounter any sort of stresses that would break Bing’s 19-ish thousand pounds of static loading, then I assure you your chassis will be in pretty dire straits. At that point your suspension should be the least of your worries.
As to fatigue loading the only factors affecting these are the loading factor, loading gradient and surface factor. For machined surfaces that’s about a 0.8 surface factor, loading gradient is gonna be equal to 1 or close to 1, so lets assume .9 for safety sakes. The threads are in a combination of axial and shear so lets be conservative again and use a loading factor of 0.9.
That gives you a combined fatigue factor of 0.648. Multiplied by the 19k-ish pounds, you get like 12,000lbs. Lets say like the hardcore drivers we all are here, that our cars have a full interior, full tank of gas, and that the driver is a chunky individual. You’d have to be pulling 4G’s or doing something incredibly dumb to get to the end of these components.
Hell, since it’s ultimate tensile and it’s a ductile material, lets say HALF for yield, and yield is for sure gonna be way more than half, you STILL can’t get anywhere near the limit of these.
Nuff benchracing, kthx? Engineering isn’t being an emo. We don’t try to be hardcore for the sake of being hardcore. Ideally all your parts should be able to take the same amount of abuse, and if something should be able to take more it should be your chassis NOT your suspension.
“Engineering isn’t being an emo”
hahah i love it! i’m fucking glaud one of the advanced engineering students finally commented on this. Like i asked before, to Ian, what formal education do you have.
Your dad builds air planes, ok…my dad was an electrician and now teaches electrical engineering…Does that make me an expert in either feild? No, sure i can wire a light and a recepticle but i’m in now way, shape or form an authority or have the ability to act like i know what the fuck im talking about.
SO in the future, keep it to yourself, it’s been proven over and over again.
“it’s better to keep your mouth shut and everyone assume you’re an idiot, then to open your mouth and prove it”
yes ian and bob that was directed at you.
Ian, Bob, no more speculation until you guys find another multi-link suspension component
for these cars where the company has been as forthcoming about the material inputs and
specs of the rod ends.
until you prove that there are other products that offer better rod ends or higher spec materials
this arguement is pointless. I have provided many examples of products that are using lower end
materials than the ones i use and it still doesnt satisfy you.
i dont have to build the greatest product ever, i am only trying to out-build what is available now.
so far, neither of you guys has provided any numerical or product based evidence to disprove me.
The only attack here is on my knowledge of metals which has nothing to do with the product and is likely to
cloud peoples ability to make an objective decision.
If anyone has any problems with the materials or rod ends i am using then you can go buy a product that
costs upwards of twice as much and uses lower quality inputs, It really is that simple.
Thread is unlocked, but moved.
The vendor’s section are at the discretion of the owners, Bing could have
locked and deleted all of this crap long ago, so don’t bitch at him that its
no longer there.
Furthermore, it appears that bing is using materials equivalent or better
than the competition. Therefore, his products are as good or better than
the competition. If you still feel these are unsafe, then stick to OEM.
If you want to continue this debate as a technical one, go ahead, but keep
the personal insults to yourselves and backup your comments with facts
where applicable.
We’re all adults here, lets act like it.
thank you for that,
you would think that people who are supposedly engineers would have used some sort of math or engineering-speak to substantiate such claims.
You have no idea what static load test they performed … was it a pull test? was it a 90 load test? did they call a ‘fail’ after it broke or a specifc elongation % ?? you don’t know so you can’t say…
how does it being a 15year old car change physics ? that you shouldn’t worry about over building? does that mean that you’d willingly use a set of 1/8" alloy camber plates over a set of 5/16" ? or use a 5.8 bolt to hold your belts in instead of 10.0?? It’s not the static load I’ve been commentiong on ( beyond the equal thread pitch size comparisons ), it’s the dynamic impacts that these parts see daily. Static loads are great… if the car is not moving or their is a constant loading being applied without change. but your suspension is NOT static…
4G’s is not that out of range for a wheel that moves up and down in a fraction of a sec. over a pot hole. or kisses a curb in a slide… point being why use a 19K pc when you can use a 54K pc for ~ the same price?
and lucky… as always you ADD so much to the converstation everytime you open your mouth…
I wouldn’t even be in this thread, if my name wasn’t brought up repeatedly when I wasn’t even posting… Contrary to popular belief I don’t like arguing…
Lucky we had the over engineering argument like 2 years ago, we beat it to death. It can wait for another day (or year).
Prove that I’m an idiot? I’m pretty sure both BAS and I make valid points. There isn’t anything saying otherwise really…
Bing notice how the ends aren’t aluminum? And I can garuntee those are not driven in the winter… I mean really, how many built 996’s do you see floating around in Canadian winters.
Besides, the feedback is going to be smaller on their performance based on the fact that there are less of them around.
Just because the application works for one type of car, that operate in certain conditions does not mean it applies to all vehicles in every condition…
Has anyone noticed the stock parts are 15 y/o rusty stamped, crimped and bent out of cheap sheet steel?
Has anyone noticed that Bing backs his stuff up?
He’s building the same parts as the “Big Name” companies and using the same parts and selling for less…seems simple to me.
its in teh catalogue, right after the rod ends… i dont have the catalogue here at work but i have it at home.
they go through all the formulas and wonderful math that you would expect a company like that to go through being that they are ISO 9001…
but hey, maybe only one person at QA1 knows about it, since you say all you need is one person to be familiar with ISO standards to be certified…
bob, the rod ends on those Porsche links are QA1 XM series rod ends that i have in stock here that i use on all of teh multi-link.
the AMR aluminum rods ends i have AS AN OPTION use the same teflon kevlar liner and are built with greater cross sectional thickness to meet or exceed the specs of the steel rod ends.
as i have said in virtually every post so far… if you arent comfortable, get the steel ones.
have you guys found a product that offers better rod ends or a company that is more forthcoming with said information yet?
thank you mike,
and good point, i should link this:
my warranty policy
when you guys are looking for the elusive comapny that is using equivalent inputs you might also search for a company with a clearly stated warranty policy… i dont think you will find one of those either.
did you get pricing on these pieces?
i have, and i can tell you the price is not the same at all…
they are also totally different sizes as i said already when you compared those part numbers
BAS, IE IAN pm
“it’‘s hilarious, you don’'t reply for a what? a week… then wen
someone with a modecum of knowledge pipes up with a rebuttal… YOU decide to
stick your greasy, smarmy nose into it y adding what? idiocy and
stupidity… you want to start something with me, do it in person… you puss”
what was my comment about “keeping your mouth shut and letting people thinking you’re an idiot instead of opening it and proving them right?”
funny i’d expect a pm like that from a 19 or 20 year old that lives at home with his parents not a 38 year old. Good job ian…
I wanna thank all the guys in Alberta and Dave in Massachusetts for picking up the aluminum multi-link arms even after reading this thread and deciding that ian and bob dont know what they are talking about.
whats more, ian or bob, if you guys want the phone number for the facility that builds these components you can have it and talk to the fabricators yourself.
i was in again today to pick up more stuff and was advised that if you have serious concerns you can call them directly so that they can call you a moron too…lol
chris Bradnam is the guy you wanna ask for… maybe pm me and i’ll give you the number because i dont wanna post it here.
All multi-link is boxed for shipping, more sets are coming this week for those interested.
bye
As per the ther request of the mods time and again and per common sense. I chose to take your insipidness to PM… obviously you seem to need some sort of fourm or public support for your dullardly behaviour… However my last statement does stand, you seem to have an issue with me, yet you never broach it; you just ooze in to a thread to make an insipid attack on me, with no basis and nothing to add to the topic… then attempt to act like you sohow made the thread complete by doing so…
IF you have an issue with me, then take it up with me in person… I’m pretty sure no one here really wants to see you being a power puff girl over and over again , as you have been doing for the last what? 12-6 months?? and yet you’ve still to come out with a reason for this animosity and you obviously have not had the courage gathered up over the last year to even PM me or get someone to tell me WHY you act like this. Now your cry for attention from me has finally come true… so, you HAVE my attention now… what is your issue with me. or are you just playing internet retard…
BS i quoted two different sizes in both diameter and thread pitch for both the cromoly and Alloy… both times the cromoly came out well ahead… and if the cromoly is THAT much more then the alloy their is something seriously wrong… as aluminum is more money then cromoly per lb in any form.
[quote=“bing”]
did you get pricing on these pieces?
i have, and i can tell you the price is not the same at all…

I’ll take that number thanks… Just so I can call them and tell them what a crock of shit they’ve been telling you or that you’ve been ‘spinning’ to yet again sell sow’s ears as a silk purse. In between there I’ll find out the real story.
I’ll be waiting for Mr. Bradnam to start the name calling as well…
all im seeing her is ppl who are jelous that bing thougt of something before they did and now it there way of feeling cool about it. I’ll be buying bing’s suspension and im recomending it to anyone who asks for it .
thats my input for this thread, and my beliefs for his product. anybody has anything to say about what i have said can adress me in person
farmer
I’d like to thank Bing, Ian/BAS and Bob/TM for giving me a solid 30 minutes of entertaining reading.
And also for inspiring me to buy a complete set of Bing’s multi-link.
That is all.
would everybody shut the fuck up, buy it dont buy it , just stop tlking , Ian, Bob and Bing have all made vaild points and have every right to do so , all the guys in here bitching have yet to realize that they just probably learned more from this post than most that are posted here , things will get out of hand when people come in here and make personal attacks, "look at me im gonna post a pm someone sent me, yet i will make comments about people being immature " like fukc off guys seriously , what is wrong with questioning certain things? i questioned the strength of these aluminium rod ends, but guys , bing has a disclaimer on his site right under the multi link, OFF ROAD USE ONLY, um if these break on the street too bad , he gives u a disclaimer.
