If needed, I have a pair of LCA's from my '06 LSJ that need to find a new home. $140 shipped for the pair.

 

idont know if thats really all that truth. i guess it depends on the grade but i mean a lot of guys that put roll cages in and use 4130 chrome moly tubing. i mean if it was brittle i dont see why you would put this in your car if your using a roll cage for safety.

 

Are the 05-07 SS FE5 control arms differnt from the 08+ SS FE5s? I thought I remeber reading that the 08+ control arms are made from a lighter material and have been designed slightly different to try and reduce wheel hop. If that's the case I am going to try and look for 08+.


Eh knowing zzp it will probably be another year or so before they come out if they actually do go through. I'd feel much safer using a factory stlye control arm, than one from a shop where the quality control of welding and materials is questionable

 

I never heard that, but you never know. Where did you read that information?

 

its not true. I have noticed a variation of a few thousands on later 07-09 control arm ball joint shafts, and the durometer of the leading bushing may have changed;some I have our different, but the trailing one did not. So bottom line ? Just the same, and the company that makes them for GM in Warren Mi is not making any more last time I checked...so inventory is all that remains...

its rare these days that folks use chromalloy in cages. Back in the day there was a wt saving advantage when you could use smaller o.d tube/wall if it was chromalloy, but that loophole got closed. Also if welds are not normalized in chromalloy fabrication bad things can happen . So most rules makers just ask for DOM ms tube.

In a wreck the cobalt flca bends and the knuckle breaks. Thats the way it was designed. But that alloy arm sure dont flex, and is plenty strong. Its just the oem bushing doesnt last long which is why OTTP came up with the weatherproof solution.

I think fabricated chromalloy flca answer a question no one asked, and 4 sure no one here will pay for.

 

I remeber reading a thread a while back on here where it was said, but good to know that they are the same. No confusion on getting the right ones.

Do you know if GM used the same supplier for all SS control arms? I doesn't seem like service parts such as control arms would be through being produced. Services parts are supposed to be availabe for 15 years for a vehicle. If that's the case and they are through, maybe it's time to get them sooner than later just to be sure to get a set

 

if this chromalloy you speak of is being used a reference to chromoly, which zzp is making their control arms out of. Then my friend you are about as dumb as the chair you are sitting on.

Do me a favor, stop using the internet. But before you do, e-mail Lg motorsports, Pratt and Miller, or hell why not, Wolfe racecraft! ask them which is a better material for a cage, chromoly or DOM?

 

check the rule book before you start mouthing off and look dumb buddy. Lou Gigliotti (a personal friend of mine for what, 30 years?) has built any number of World Challenge cars, all his cages were Mild steel.... the rules makers dictate the materials...guess I had better go look at the ALMS rules, not that I care....


OH FERRETS Guess what? YOU SHOULD START USING THE INTERNET: Safety Devices in the UK one of the top manufacturers of FIA roll cages says:

"FIA ROLL CAGE MATERIAL
CDS Carbon Steel
Otherwise known as Cold Drawn Seamless Carbon Steel, this is the material is used to manufacture all of our standard motor sport and 4 x 4 roll cages as it conforms to FIA material specification requirements and offers good elongation and weld-ability, which are key. Compared to T-45 it is a very cost effective material.

ERW mild Steel
The full description is Electrically Resistance Welded mild steel. Because this material does not have a high enough tensile strength value to comply with article 253 section 8.3 of the FIA regulations relating to material specification, it is only used for non structural applications such as roof racks whre a durable product is required.

Cr (Chrome Molybdenum) Steel
Although popular with some roll cage manufacturers, we do not use Cr in any of our tubular products. This is because the properties of Cr Steel are not considered a particularly suitable as achieving a constant quality is problematic and its ductility is far less effective in deformation than T45.
"
so you are WRONG Imagine that?

 

can you put le3 or le5 control arms on a le1 suspension?

 

Good question, and AFAIK and based on the discussion I had with the SS control am vendor, GM purchased inventory, and they look at the annual consumption rate I am sure, and make business decisions based on that. Since the bankruptcy, I have no idea where that puts anything. For sure the control arm bushings are in short supply, along with some other LSJ/LNF parts....ya never know.

I have been depleting my control arms supply at a good rate and frankly at some point I will keep spares for my car and thats that....

4 sure. The LE5 must be replaced in pairs as the ball joint position in the arm is different so there would be unequal wheelbase and caster side to side if you did just one....not that the car would mind that much! Most Cobalts and RL are not square from the factory. Mine is out of square about 10 mm at the front hub from the rear, and I have not gotten round to fixing it...

 

cool where are the time attack arms!!!!!

 

Time attack arms are OEM LE5 with spherical joints in trailing and uhmw/steel in leading positions...you can get them in an updated better version from OTTP. Seeing as you asked here is a piktar of the Time Attack car under construction in our raceshop May 16 2004. Note the FE5 arm on a prototype Ohlins strut.

 

Hey Qwik, maybe you should contact Lou, maybe he is unaware that his cars have mild steel cages, The guys at Compuware might be interested to find out that they are supposed to have CrMo cages and PM only gave them plain steel.

Perhaps the Grand American Series, American LeMans Series, and damn near every other automobile racing sanctioning body that uses FIA rules should know that they should use CrMo because its "better".......I am gonna call the FIA first thing tomorrow morning and let them know that their rule that essentially does not allow any alloyed steel is bullshit since Ferret says CrMo is better.

 

I love when you and Brad are "corrected" John. epic pwnage ensues.
